Digital Absolute or Gauge Pressure Measurement and Control Series Overview Alicat Scientific P-Series digital pressure gauges accurately and rapidly measure the absolute or gauge pressure of process gases and liquids. PC-Series pressure controllers provide precise control of pressure via customized high-speed proportional control valves. For backpressure control, the PC Series is available with downstream valves and inverse valve control algorithms. Alicat’s PC3-Series pressure controllers incorporate a remote pressure sense port for control of flow into a process that is distant from the controller. Each instrument within the P/PC/PC3 Series is also available with corrosion-resistant wetted materials and stainless steel flow bodies. These devices belong to the PS/PCS/PCS3 line of pressure gauges and controllers for corrosives. All pressure instruments come with NIST-traceable calibration sheets. Alicat backs every P/PC-Series pressure instrument with generous customer support, including free technical phone support, prompt recalibration service and a lifetime warranty. Alicat P/PC-Series pressure gauges and controllers feature large integrated displays. PC-Series controller touchpads enable setpoint control access and PID valve tuning. The P/PC Series comes with both analog and RS-232 digital communications. Extensive customizations are available, including Class 1, Div 2 ATEX/ CSA ratings for use in hazardous environments and battery operation for portable gauges (PB Series). Applications Alicat Scientific P/PC-Series digital pressure gauges and controllers are used in a variety of industries, from gas analysis and filter characterization to vacuum coating and process control. A low 200:1 turndown ratio, available 0.125% accuracy, 0.2% full-scale repeatability and <100 ms control response times ensure optimal performance of pressure control processes. The P/PC Series is available in full-scale absolute pressure ranges from 0-30 psia to 0-500 psia, and in fullscale gauge pressure ranges from 0-1 psig to 0-500 psig.

Technical Data for PC, PC3, PCR, and PCR3 Single Valve Pressure Controllers Alicat PC-Series pressure controllers allow the precise control of absolute, gauge or differential pressure. These units can be configured for vacuum pressure or backpressure control. PCR-Series pressure controllers are best for flows greater than 20 lpm. PC3 and PCR3-Series pressure controllers are fitted with an external pressure port for sensing and controlling pressures at a remote point in the system.
