The Model 7350 High Pressure Pneumatic Controller and Model 7615 High Pressure Hydraulic Controller provide a safe, easy to use, and effective means of automating high pressure test and calibration of a wide range of pressure measuring devices. In control mode, these controllers simultaneously measure and control pressure, and can be used for the calibration and testing of pressure gauges, transducers, pressure switches, and production pressure instruments.
The Model 7350 and Model 7615 controllers use a quartz transducer for unmatched performance in conducting automated high pressure testing and calibration. Precision levels are 0.01% of full scale for pressures to 20,000 psi(1400 bar) and 0.02% of full scale for pressures above 20,000 psi (2750 bar). Stability is 0.01% of full scale per year, providing for an annual recalibration interval.
- Pressure ranges up to 10,000 psi (700 bar)
- Precision to 0.01% FS
- Control stability 0.007% FS
- User-friendly menu driven operation
- RS232 & IEEE-488 interface
