Product Overview

This is the CSM cutter / SITRANS F control transducer used in the Siemens SITRANS F M MAG 1100 flow measurement assembly — the small electrical unit that sits in a crane's or drilling rig's measurement circuit and passes the reading back to the controller. When it fails, the reading it feeds goes with it, so most of these leave us as urgent crane spare parts rather than as planned stock. It takes the same position as the unit it replaces, and as a crane parts supplier we check the number you quote against your machine before the part is dispatched.

Typical buyers are fleet maintenance teams keeping a crane working, workshop fitters swapping a failed unit at the bench or at the machine, and dealers holding crawler crane parts for customers of their own. It replaces the failed unit in the same position, and it is ordered by the number printed on the old part rather than by the machine model alone, because two machines of the same type can carry different sensor versions. If you are rebuilding a whole control circuit rather than replacing one unit, tell us what the machine does and we will price the list together.

Specifications

Order Numbers & Label Check

Order by the number, not by the machine. The order number for this unit is 7ME61102RA202AA1, and the listing carries 232313H044 alongside it as a second reference, together with the CSM cutter designation. Read yours straight off the old unit rather than from a manual or an old invoice, and quote it exactly as printed, including every letter — a trailing character is often what separates one variant from the next. While the old part is still on the machine, that is the moment to check the construction machinery spare parts number against what you intend to order.

On the unit itself, the factory label records the order number, the sensor serial number, the sensor material and the calibration factor for that individual sensor. Photograph the label before the old unit comes off the machine: the calibration value belongs to the sensor you are removing and settles any question about the reading afterwards. If the label is worn, painted over or missing, send a picture of the unit in place and of the machine plate instead — crane parts are identified by position and machine as often as by number.

Machine Coverage & Applications

• FUWA crawler cranes — the family we quote for most often, from the QUY35 class through to the QUY1250, with the part matched to your machine rather than to the tonnage class.
• SANY rotary drilling rigs — measurement and control components for rigs working alongside the same crane fleets.
• XCMG and ZOOMLION machines — electrical and safety components for these fleets, supplied against the machine model and the part number you give us.
• Where the unit sits — in the measurement and control circuit, wired back to the controller or display that reads the value.
• Work it turns up on — crane erection and lifting on infrastructure sites, port and terminal handling, and mining or steel plant maintenance fleets.
• When it is ordered — after a failed reading, during a planned electrical overhaul, or as held stock for a fleet that cannot wait on a crane spare parts order.
• Mixed fleets — crawler crane parts, hydraulic items, filters and seals for the same machine can be quoted in one reply from a single crane parts supplier instead of from separate suppliers.

Installation & Commissioning

1. Isolate the machine and prove it dead before you break any electrical or hydraulic connection: lock out, then release the line pressure and drain down.
2. Photograph the wiring, the pipework and the unit's position, and keep the old unit and its fasteners on the bench as a reference — on construction machinery spare parts work the removed part shows you the orientation and the fitting pattern.
3. Remove the old unit, then clean and inspect the mating faces and threads, and fit new seals rather than reusing the old ones.
4. Fit the replacement with its supplied seals, keeping the same orientation as the old unit and the label readable for the next person who has to identify it.
5. Reconnect the 24 V AC/DC supply, checking polarity and cable routing, and keep the cable clear of hot or moving parts.
6. Restore pressure and power gradually, then watch the reading on the controller or display. Where a calibration value is stored in the transmitter, confirm whether it has to be re-entered for the new sensor.
7. Run the machine through a short loaded cycle and check that the reading stays steady under vibration before you hand it back over.
8. Record the new sensor serial number and the fitting date in the machine's maintenance log.

Ordering, Delivery & Support

1. Send the number and the quantity. Quote the order number from the old unit, the quantity you need and your machine make and model. One unit is usually enough for a repair, and batches are quoted the same way.
2. We confirm fitment and availability. Our engineers check the number against the machine and come back with a straight confirmation or with the alternative that does the same job. If a construction machinery spare parts number has been superseded, we say so before you commit.
3. You receive the quote and the terms. Pricing is quoted per order, with the terms set out in the reply: T/T and Western Union are both accepted, and other terms can be agreed for repeat business. The minimum order for standard electrical parts is one unit.
4. Stock or production. Most electrical parts ship from stock. Custom or non-stock items are produced and dispatched within roughly 3–4 weeks of design confirmation.
5. Packing. Units are protected inside the case and packed in secure crates to survive export handling, marked to be kept upright. Tell us if the packing has to suit a particular onward shipment or a specific stores system.
6. Shipping. Standard international shipping generally runs 7–15 days by courier, with express delivery of about 3–5 days available at additional cost. We ship through Shanghai and Dalian on EXW, FOB, CFR or CIF terms, and we handle the export paperwork that goes with heavy equipment parts shipments — confirm the destination and the terms you want and we will put them in the quotation.
7. After-sales support. Electrical safety system parts carry a 12-month warranty covering manufacturing defects; improper installation, unauthorized modification and damage from extreme environments are excluded. Our engineers support installation, calibration and troubleshooting on site or remotely, guidance for emergency repairs is available around the clock, and faulty parts can be sent back for repair with a typical turnaround of 5–10 business days.

Calibration & Sensor Records

• The calibration factor belongs to the individual sensor and is printed on that sensor's own label together with its serial number, so it travels with the unit rather than with the machine.
• Photograph the old label while the unit is still fitted. Once the part is off the machine and the label is worn, painted over or lost, that value cannot be read back from the part itself.
• Whether the factor has to be re-entered depends on the controller, transmitter or display that reads the sensor. Send us the make and model of that unit with your order and our engineers will confirm the procedure for your machine before it ships.
• If a stored calibration value is left at the old setting after a correct replacement is fitted, the machine can read with an offset — the symptom is a wrong reading rather than a failed unit, which is what sends a fitter back to the machine a second time.
• Record the new sensor serial number, its calibration factor and the fitting date in the machine's maintenance log, so the crane parts history for that machine stays complete and the next swap starts from a known value.
• Keep the old label with the machine file as the record of the reading before the swap; it is the reference if the display value is ever questioned later.
• On fleets running the same measurement circuit on several machines, keep the record machine by machine. A sensor moved between two cranes carries its own factor, and the value stored on each controller has to match the sensor actually fitted to that machine.
• Tell us at the quotation stage if your site procedure requires the calibration check to be signed off, and we will set out what the fitter has to verify — our engineers handle this side of heavy equipment parts on site and remotely every week.

Discontinued & Hard-to-Find Parts

When a machine is out of production but still working, the part number matters more than ever. If the number you have is discontinued or hard to trace, send us the machine model together with that number: we search our supplier network, confirm what is genuinely available, and give you a straight answer before you commit. Where the original is no longer made, we set out the alternatives we can actually supply, or an upgrade path, and coordinate samples, inspection and made-to-order work with the suppliers we buy from. Sourcing, consolidation and export handling stay with us.
