PRESSURE TRANSMITTER

 PRESSURE TRANSMITTER RPT-5F

FEATURES:

*Hammer union pressure fitting, resistant to shock and vibration, suitable for harsh environment;

*Specially designed 4 strain gauge structure, low resistance output,ensure

  long-term stability;

*The two-stage amplifier circuit match with micro strain signal processing;

*The special strain gauge location to ensure the return to zero and shorter response time;

* Use for cementing, fracturing and acidizing in oil well.
