Part No. 2080014
0–20″ WC Photohelic gauge (3020SGT) with 4–20 mA transmitter output for differential pressure monitoring, control, and remote integration.
The 2080014 Photohelic Gauge – 0–20″ WC with 4–20 mA transmitter output (3020SGT) combines differential pressure measurement, solid-state switching, and analog signal transmission in a single, durable unit. Designed for continuous monitoring and control of air and gas systems, this model provides a clear analog dial for local display and a standard 4–20 mA output for remote monitoring or integration with PLCs, building management systems, or SCADA networks.
Its adjustable set points control high and low pressure limits, making it ideal for dust collection systems, HVAC applications, and other processes where maintaining proper differential pressure is critical for efficiency and safety.
Range: 0–20″ WC
Display: Analog dial with dual set-point indicators
Function: Combines differential pressure gauge, pressure switch, and transmitter
Output Signal: 4–20 mA proportional to measured pressure
Switching Type: Solid-state, SPDT (per set point)
Applications: Filter monitoring, clean/dirty air differential control, automated dust collector cleaning, remote pressure monitoring
Enclosure: Durable housing with clear lens
Power Requirements: Per manufacturer specification (varies with coil and output options)
