Elektrische drukkalibrator

Inleiding

Source, simulate, and measure mA signals with this electric pressure calibrator that features an integrated electric pump for one-handed pressure calibration up to 150 psi. Ideally suited to calibrate high-accuracy transmitters, pressure switches, and gauges, the unit features a backlit display and a rugged, handheld design.

Applications

• Petro-chemical
• Oil and gas
• Pharmaceutical
• Water and wastewater
• Food and beverage
• Power generation

Features

• Pressure measurement from internal or external sensor
• Sourced/simulated or measured mA values
• Electric pump for one handed pressure calibration
• Best in class pressure measurement uncertainty of 0.025%
• Measure and source mA with best in class 0.015% accuracy
• Precision pressure adjust vernier for accurate pressure calibration
• Variable release rate bleed valve for easy pressure adjustment
• Programmable pressure calibrator pump limit: eliminates over-pressurization and allows the user to program target pressures for pumping
• Programmable 3-tiered display for maximum flexibility when displaying pressure, temperature, and electrical parameters of your choice
• Display backlight
• Damping, min/max, and % error function
• Source mA with simultaneous pressure measurement to test valves and I/Ps
• Simulate mA signals to troubleshoot 4-20 mA loops
• Test pressure switches with built in switch test function
• Power transmitters during test using 24 V loop supply with simultaneous mA measurement
• Proven cleanout ports reduce pump failures
• Moisture trap included with the unit helps mitigates risk of moisture damage
