The TESCOM™ ER5000 Series of electropneumatic controllers brings precise closed loop pressure control to a wide range of applications. The unit is a microprocessor based Proportional, Integral, Derivative (PID) controller, providing localized control and automation with exceptional accuracy (0.1% FS) and rapid response time (25 msec) to ensure desired pressure even as system process parameters change. Eliminating deficiencies of mechanical pressure regulators such as droop and decaying inlet effect, this easy step toward automation also reduces human error and fatigue and provides remote control and data acquisition capabilities. The product can be used as a standalone unit to control the pressure of clean, dry inert gases from 0-100 psig/0-6.9 bar, or can be connected to any pneumatically actuated regulator or valve. Used with TESCOM regulators, the system provides pressure control of gases and liquids from vacuum to 30,000 psig/2,068 bar, with a CV of up to 12+.
