Sensors of excess pressure discharge
Measuring equipment of excessive pressure-discharge МТ100М (Ех)
Sensors of excess pressure discharge MT100M (Ех)
Compact execution with correction of zero and range.
Sensors of excessive pressure of the MT series are intended for continuous and uniform transformation of pressure of liquids, gas, steam and so on in the unified current output signal (0-5 mA, 4-20 mA). Sensors work with the showing and data-acquisition equipment, regulators, in systems of automatic gaging, in nodes of the heataccount and other devices of automatic equipment.
KPM 3 module
All sensors of excessive pressure MT100M (Ех) are temperature-compensated on "0" and on all range of measurement, and also the possibility of adjustments "0" and range is provided in each sensor. Sensors are convenient for mounting, are not critical to change of polarity at connection, have the DIN 43650 connector. Is an analog of KRT pressure sensors.
For installation of sensors, we recommend to use specially developed switching instrument KPM-2 module the valve having drainage (drain valve). Detailed information on the module is in the section "Auxiliary equipment".

Circuit diagram of connection of sensors.
An electric power supply of sensors is carried out from a source of a direct current from 15 to 42V, but not less, determined by a formula:
where Unmin - the minimum allowable stress of a power supply at Rn loading, V;
Rn - resistance of loading, (kOhm).
Umin - the minimum allowable stress of a power supply without loading, equal 15V;
Iv - the upper extreme value of an output signal equal 20mA.
Rh - loading resistance. Polarity of a power supply of the sensor can be chosen randomly.
Checking is made according to the recommendation of MI 1997-89, but with connection to terminals 1-2 sensors.
