Temperature Sensor

Accurate temperature readings are critical to accurate level measurements because the speed of sound changes, depending on air temperature, and all Siemens Milltronics Echomax and ST-H transducers have an internal temperature sensor.

If the following conditions apply, a separate TS-3 temperature sensor will ensure optimum accuracy:

the transducer is exposed to direct sunlight (or other radiant heat source)

the transducer face and monitored surface temperature differs

faster response to temperature changes is required

TS-3 is not deployed.

mA Input [MR 200 only]

For more information, consult the Transducer (P004) and mA Input Parameters (P250, P251, and P252) in the parameter reference section.

mA Output

For more information, consult the mA output parameters (P200 to P219) in the parameter reference section.
