Pressure transmitter housing high bottom

The pressure transmitter housing high bottom is ideal for precise measurement of differential pressure in ventilation and air conditioning systems, clean rooms, or for filter monitoring. Eight switchable measuring ranges and two output signals (0 to 10 V or 4 to 20 mA) ensure flexible application options. The robust housing with connections on the underside complies with protection class IP67 and is easy to install, even in confined spaces. Manual zero point adjustment ensures accurate measurement results at all times.

Pressure transmitter - Important assembly instructions
[A] Negative pressure P1 (+) is not connected, is open to the atmosphere on the air side P2 (-) connection in the duct [B] Filter: P1 (+) connection before the filter P2 (-) connection after the filter [C] Fan: P1 (+) connection before the fan P2 (-) connection after the fan [D] Volume flow: P1 (+) dynamic pressure, connection in flow direction P2 (-) static pressure, connection free of dynamic V = k · √Δ p (V = volume flow | k = k-factor | Δ p = differential pressure [Pa])
The device is supplied with the connection set (hoses and connection nipples). The pressure connections must be connected correctly according to the required monitoring type (see diagram). Before commissioning, check the pressure lines and electrical wiring for leaks.
