PressureBox

A versatile pressure sensor equipped with 1 or 2 pressure sensors and the possibility to choose amongst predefined pressure areas 0-7000Pa. The measured pressure can be read through the 0-10V/4-20mA output signal or via ModBus protocol. If you use the ModBus protocol the Pressurebox can be used as compilation point for 2 temperature sensors (NTC or PT1000) and digital inputs such as filter guard etc. All readable through Modbus.
To measure flow instead of pressure, the K-factor is entered into the pressurebox.
By setting an internal setpoint he pressurebox can be used as a simple VAV/CAV controller.
The PressureBox is available for other pressure areas, with dual pressure sensor and with or without display.
