PSID Family Digital Differential Pressure Measurement and Control alicat.com/dp Series Overview Alicat Scientific P-PSID Series digital differential pressure gauges accurately and rapidly measure the pressure differential between two points in a process using separate dead-ended pressure sense ports. PC-PSID Series pressure controllers provide precise maintenance of the differential pressure in open systems via customized high-speed proportional control valves. PCD-PSID Series dual-valve differential pressure controllers control differential pressure within closed systems via dedicated inlet and exhaust valves, eliminating the need for additional bleed valves and wasteful outgasing. These series are also available with remote sense ports for maintenance of pressure in volumes that are distant from the controller (PC3-PSID, PCD3-PSID). Each instrument within the PSID Family is also available with corrosion-resistant wetted materials and stainless steel flow bodies in the PS/PCS/PCS3/PCDS series. All pressure instruments come with NISTtraceable calibration sheets. Alicat backs every PSID-Family pressure instrument with generous customer support, including free technical phone support, prompt recalibration service and a lifetime warranty. Alicat PSID-Family pressure gauges and controllers feature large integrated displays and both analog and RS-232 digital communications. Controller touchpads enable setpoint control access and PID valve tuning. Extensive customizations are available, including Class 1, Div 2 ATEX/CSA ratings for use in hazardous environments and battery operation for portable differential pressure gauges (PB-PSID Series). Applications Alicat Scientific PSID-Family digital differential pressure gauges and controllers are used in a variety of industries, including gas analysis and filter characterization. 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 measurement and control processes. The PSID Family is available in full-scale differential pressure ranges from 0-1 psid to 0-100 psid.

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. Standard Specifications (Contact Alicat for available options.) Performance Full scale pressure < 2” H2O...
