The transmitter 2010TC of the Multi Vision - series is a mass flow measuring device with an analogue or digital output signal for the process industry. The transmitter 2010TC measures accurately and simultaneously the differential pressure, the static pressure and with a RTD in four-wire technique the process temperature of aggressive and non-agressive media. The electronics calculate the compensated mass flow using these dynamic fluid conditions.
The measuring ranges are from 10 mbar to 100 bar (1 kPa to 10 MPa), each for the nominal pressure ranges 20, 100 and 400 bar.

The transmitter has a modular design and consists of the differential pressure sensor module with an integrated electronic matching unit, an amplifier with control unit as well as an input for a RTD in four-wire technique for process temperature.The completely welded sensor module is a twin-chamber system with an integral overload diaphragm, an internal absolute pressure
sensor and a silicon differential pressure sensor. The absolute pressure sensor, which is only exposed to the pressure at the high
pressure side (Å) , acts as a reference value to compensate for the static pressure. The differential pressure sensor is connected via a capillary tube to the negative side of the sensor module. The applied differential pressure (dp) is transferred via the separating diaphragm and the fill fluid to the diaphragms of the silicon differential pressure sensor.
A minimal deflection of the silicon diaphragm changes the output voltage of the pick-up system. This pressure proportional output
voltage is digialized by machting electronics and fed to the amplifier. The amplifier linearizes and temperature compensates this signal before it together with the values for dp, p and T is converted into a compensated mass flow proportional signal. Apart from the
mass flow (qm) the values dp, p, T and qv are also available for further use.
