Product Details
The very small measuring amplifier type M2428-91 converts the measuring bridge directly to a 4…20mA 2-wire signal.
The M2428-91 works with a resolution of 12 bit, is pre- calibrated and connected between the sensor supply line and signal acquisition instrument (e.g. PLC).
The robust housing confirms the protected class IP67 and allows application in rough environments.
Any range within the measuring range can be programmed by the customer. E.g. 45kg to 420kg = 4 to 20mA within a calibrated range of 0 to 500kg.
It is possible to tare the M2428-91 in the range of 0…30% of full scale from outside with a simple permanent magnet. Within this tare range the full measuring range remains available.

Load cell type M2428-14
Code: Product Details The M2428-14 is a low-cost load cell to measure weights or forces in the range of 25kg (~250N) to 30'000kg (~300'000N). The bending beam consists of a strain gage sensor with integrated electronics to convert the force or weight to a 4…20mA signal. There is no need to use external, sensitive strain gage amplifiers or signal conditioning devices. A cell connects directly to any 2-wire sensor input of process control computers or other control equipment and displays. The bending beam confirms the protected class IP67 an delivered with open cable ends. Any range within the measuring range can be programmed. E.g. 45kg to 420kg = 4 to 20mA within a calibrated range of 0 to 500kg.
