Pneumatic-electronic transducer.
The P37 is a Pneumatic-electronic transducer that converts a 2-13 psi input into a proportional Pulse or 0-10VDC output and therefore replaces both the P35 and P36. For ease of use the board is programmed for 3-8 psi Pulse output selectable from the MODE DIP SWITCHES in Direct or Reverse Acting mode. Custom pressure ranges can be adjusted in the field with qualified pressure gauge and the appropriate DIP Switch setting.
Safety feature, monitors the quantity of air flowing through the heater, adjusts the heater’s capacity to match the air flow available and shuts the heater down in case of a total loss of air. This feature is available only on heaters equipped with full SCR.
