Digital Pressure Controller calibrates low-pressure gauges.

Model 7250LP incorporates 0-10 in. H2O range and 0-30 in. H2O range into one instrument and maintains set-point pressure to within ±0.0004 in. H2O. In Active mode, unit continuously controls set-point and corrects for small leaks and temperature effects. In Passive mode, user defines upper and lower limits where controller will deactivate once pressure is within limit settings. IEEE-488 and...

PID Pressure Controller suits washdown applications.

Proportional/integral/derivative pressure controller incorporates sanitary clamp process connection to prevent media from entering controller. Pressure measuring element consists of 1 piezoresistive sensor that compares measured pressure to setpoint and sends corrective 4-20 mA output signal to final control element to control pressure. Push buttons (4) located below LCD display control operating...

Pressure Regulator is a zero leak device.

Unit regulates pneumatic or water pressures in applications that require little or no flow. Output is adjustable with ranges from 0-3.5 psi to 0-100 psi with 15 turns of resolution. Maximum supply pressure is 150 psi with maximum air flow of 1.0 scfm, and maximum water flow of 0.2 gpm. Non-bleed, non-relieving type regulator is for use in medical equipment, air bearings, and custom machinery....

Controllers work with heat pumps and air conditioners.

Head Pressure Controllers sense refrigerant temperatures and modulate condenser fan speed to balance high to low side circuit vapor pressure. On start up, fan is given initial hard start at full speed for 10 seconds and then slows to speed to give required condensing temperature. As ambient temperatures fall further, fan gradually slows to about 1/3 full speed to maintain bearing lubrication and...
