MTM/N 10 Miniature submersible level transmitter

Product catalog summary

Overview: The document provides technical specifications for the MTM/N 10 miniature submersible level transmitters, available in passive, active, and datalogger versions. It includes details on pressure measuring ranges, accuracy, thermal shifts, and electrical specifications.

Specifications:

Pressure Measuring Range: Available ranges are 10-20, 20-40, and 40-100 mH2O.
Overpressure: Up to 3 times the full scale (FS) or 12 bar.
Accuracy: Setting accuracy includes zero point at ±1mV and span at ±2% FS.
Thermal Shift: Zero point and span shifts are specified for -5 to 50°C.
Long Term Stability: Defined over one year, typical and maximum values provided.

Output Signal: For passive versions, typical output signals are 50 mV for 10-20 mH2O and 100 mV for higher ranges at nominal pressure with 10 V DC supply.

Electrical Specifications:

Input Impedance: Greater than 10 kOhm.
Bridge Resistance: Typically 3 kOhm.
