Product Details
- Temperature Range40 to 130 °F
Description
Proportional, high capacity, single or dual input pneumatic controller
used in conjunction with remote sensors to provide proportional (P) or
proportional plus integral (P+I) control of temperature, humidity,
pressure, or dewpoint for heating and air conditioning systems.
Replacement devices are available for Johnson, Powers, Robertshaw,
Barber-Colman, and older Honeywell controllers.
- Proportional plus integral control option minimizes offset.
- Miniature diaphragm technology provides high degree of accuracy and reliability.
- Direct Acting models can be converted to Reverse Acting (RA) function in field.
- Field adjustable compensation start point.
- Local or remote setpoint field option. Integral action cut-off provides trouble-free automatic startup.
- Transparent cover (optional) provides protection while allowing easy reading of settings and gages.
- Corrosion resistant construction.
