Alicat Scientific ISPCD | IS-Pro Intrinsically Safe Dual-Valve Pressure Controller
The ISPCD is the dual-valve IS-Pro controller, using inlet and exhaust valves for precise pressure control in hazardous locations, over 0.07 to 1,500 PSI full scale. Accuracy is as good as ±0.125% of full scale with ±0.08% repeatability. It suits dead-ended volumes and backpressure duties with non-corrosive gases in Zone 0 areas. For integration, the ISPCD offers communications of RS-232 (default), RS-485, 4-20 mA analog, Modbus RTU. Alicat lists ISPCD approvals as ATEX DEKRA 22ATEX0075 X; IECEx DEK 22.0078X; cDEKRAus DEKRA 23CAUS40-127215.
