Differential pressure controller -125 to 125 Pa - AC or DC supply


HPSP-series control differential pressure (Pa), volume flow (m³/hr) or air velocity (m/s) in HVAC applications. They can directly control EC fans, frequency inverters or fan speed controllers thanks to their PI control algorithm with anti-windup function. This makes them the ideal controller for Variable Air Volume or VAV applications. They keep the requested differential pressure, volume flow or air velocity constant, regardless of demand. This setpoint, the pressure range and all other parameters can be adjusted via Modbus RTU. Air velocity control is possible in combination with the optional pitot tube connection set: PSET-PTx-200. The four LED indicators provide a clear visual indication of the status of the controller and the controlled values. The control output provides an analogue or modulating control signal: 0-10 VDC, 0-20 mA or 0-100 % PWM. Supply voltage: 18-34 VDC / 15-24 VAC ±10 %. It can be used in the range of -125 to +125 Pa.

Frequently asked questions:
In general, the difference is the supply voltage: -M version: The –M versions are Power over Modbus supplied with 24 VDC via an RJ45 socket. They do not feature a physical out, however, there is an output value generated and read via Modbus RTU. When combining multiple Sentera products via Modbus RTU, we advise to use –M or -F series. -F version: The –F version is supplied with 18 - 34 VDC via a terminal block and features physical outputs. The -F version of the product is not suited for 3-wire connection. It has separate grounds for power supply and analogue output. Connecting both grounds together might result in incorrect measurements. Minimum 4 wires are required to connect -F type sensors. When combining multiple Sentera products via Modbus RTU, we advise to use –M or -F series. -H version: The –H version is a combination of –M and –F series. They can be supplied via Power over Modbus (24 VDC via an RJ45 socket) or via the terminal block, whichever the customer prefers. The –H series also features physical outputs via the terminal blocks. -G version: The –G version features 18 – 34 VDC or 15 – 24 VAC. The -G version is intended for 3-wire connection and features a ‘common ground’. This means that the ground of the analogue output is internally connected with the ground of the power supply. In case a Sentera sensor will be connected to other, non-Sentera branded products, we advise to use –G series.
