Air Pressure Measurement Device F1791 for Control Systems in Boilers and Power Plants

The air pressure measuring device F1791 is used for measurement and control of air overpressure and rarefaction and can be used in control systems of boiler and CHP equipment, for control of technological parameters and emergency protection, as well as in ventilation and air conditioning systems. The device provides measurement of gauge pressure, vacuum and air pressure difference in the ranges: 0,125 kPa - 6 kPa. Mounting method - panel or protruding.

For connection of impulse lines there are 2 sockets for elastic pipes of 8 mm diameter or a nipple for welding to the pipeline. Power supply voltage of the device is 24 V DC; 24 V DC with galvanic isolation from analogue output; 220 V AC 50 Hz. The device can have up to 2 electric signalling relays.

Output signal 4 - 20 mA or RS-485 interface.
