Product description

The DT7200 …Intrinsically safe pressure transmitters provide a 4-20 mA current signal in proportional to the pressure connected to their input. The transmitters are intrinsically safe devices, and they can be operated in a potentially explosive environment falling into the category Zone 0 and Zone 1.
The transmitters are available with 32 different measurement ranges, for the measuring of relative / absolute pressure and vacuum. Depending on the construction of the device, the temperature of the medium under measurement may vary between -25 °C and 140 °C, while the ambient temperature may be between -25 °C and 70 °C.
The material being in contact with the medium is KO36 steel; the sealing applied depends on the medium and the temperature of the medium, and it can be: Teflon (PTFE), Buna EP (EPDM), Viton (FKM), or Isolast 9503 (FFKM).
The transmitters are available with various threaded connections: G1/2”A / M20 x 1.5 manometer connection, and G 3/4” A front-membrane construction.
