Model 570 Flush Tip Pressure Transmitter

5x proof, 4-20 mA output, Blender Pressure Measurement

The Model 570 Flush Tip – Zero Cavity design offers an Isolated sensor assembly that virtually eliminates installation torque effect and is able to withstand pressure spikes up to 5x proof pressure and 20x burst pressure.


 All Stainless Steel construction
 Many Options available
 High Overpressure Applications
 IP-67 Rated


The Model 570 Flush Diaphragm Pressure Transmitter is designed to meet the rigorous demands placed on pressure transmitters used for well-servicing applications including manifold charge and high-pressure pump suction pressure measurements.

Features of the Model 570 flush diaphragm pressure transmitter include:

  • Flush Tip Diaphragm (Zero Cavity Design)
  • Patented* Solid Stainless-Steel Diaphragm Technology
  • Isolated Sensor Design virtually eliminates torque effect
  • Withstands 5 times Proof Pressure at 0-1,000 psis range
  • Withstands 20 times Burst Pressure at 0-1,000 psis range
  • High Accuracy (≤ +/-0.50% FSO)
  • IP67 rating (Fully welded and sealed housing)
  • Hazardous Approval Options Available

Minimizing the torque effect on the diaphragm has eliminated the need to adjust the instrument after installation. The ability to withstand pressure spikes up to 5 times the 0-1,000 psis range extends the life of the transmitter when cavitation is a risk in the system. The patented pressure sensor diaphragm technology has resulted in a very stable unit with the high performance and data integrity needed for blending in acidizing, cementing and fracturing applications.
