The DT720 … Pressure transmitters provide a 4-20 mA current signal proportional to the pressure connected to their input. The remote transmitters are available in 37 different measurement ranges, for measuring relative / absolute pressure and vacuum.
The temperature of the measured medium may vary between -25 °C and 140 °C (depending on the construction of the device), while the ambient temperature may range from -25 °C to 70 °C. The material being in contact with the medium is ceramic or KO36 steel, and the sealing may be Teflon (PTFE), Buna EP (EPDM), Viton (FKM), or Isolast 9503 (FFKM), depending on the medium and the temperature of the medium.
The transmitters are available with various threaded connections: G1/2”A / M20 x 1.5 manometer connection, G3/4”A front membrane construction.
