  • 4-20mA output
  • G1/4 male thread
  • 0.5% accuracy
  • 1ms response time
  • 4-pole connection

TheTK series of pressure transmitters are suited mainly to measure pressure in oil, air and hydraulic circuits.

They are popularly used in general process measurement applications as well as for compressors, presses and mobile hydraulics.


  • 4-20mA output
  • M18x1.5 thread
  • 0.3%-0.6% accuracy
  • 8ms response time
  • 6-pole connection

TPF pressure transmitters with a flush measurement diaphragm are particularly designed to check pressure of high viscosity fluids.

They are also used in the food industry,where substances must not stagnate in cavities.
