Type 3210- T3210 Analog Weatherproof Regulators
The Bellofram Precision Controls Type 3210 is a single-loop analog weatherproof servo pressure controller for precise electronically commanded pneumatic pressure. It accepts 4-20 mA or 0-10 VDC input signals and uses twin solenoid valves with an internal pressure sensor for closed-loop regulation. Accuracy is ±0.5% of full scale or better, and an analog monitor output provides feedback of actual regulated pressure. The Type 3210 is suited to HVAC, medical equipment, low-flow process control, vacuum applications, and other systems that need dependable analog electro-pneumatic pressure control.
