The TPAPC-500 Constant Air Pressure Controller with integrated pressure measurement sensor is designed to provide a compact low cost solution for air pressure control.

Depending on your application requirements the TPAPC-500 can maintain balanced, negative or positive air pressure within the space. This makes it perfect for VAV (variable air volume) applications such as:

  • Large residential extract systems
  • Laboratories or fume cupboard environments
  • Surgeries or operating theatres
  • Any VAV system where air volume needs to be controlled

Operating on 24V AC/DC supply the controller action is PI and caters for multiple pressure ranges (0-100Pa, 0-200Pa, 0-300Pa, 0-400Pa and 0-500Pa) which are set by the operating pressure range option switches.

It employs a solid-state temperature-compensated pressure cell with a microprocessor to provide superior linearity, measurement accuracy and control and it has 3 potentiometers for the controller setpoint (SP), the proportional band (Pb) and the minimum control voltage output (MV). In addition to the setting potentiometers, there is a 4-way option switch that can be used for setting the control output response time (slew rate).

The controller has a red LED for power on and loss of pressure fault indication and it comes fully calibrated and with a push button to calibrate to zero pressure.

Key Benefits:

  • 24V AC/DC supply
  • Selectable pressure ranges
  • 0-10V output
  • Self-calibrating at the touch of a button
  • LED fault indication
  • IP51 rated
