The SPB cavity free pressure (flat membrane) pressure transmitter adopts high-precision foil strain gauges and is equipped with various characteristic amplification circuits, such as anti-interference type, high temperature resistant type, intrinsic safety explosion-proof type, etc., making it suitable for various working environments. In addition, the cavity free structure is particularly suitable for measuring media with high viscosity.

Characteristics of SPB104 non cavity flat membrane pressure transmitter
·No cavity measuring diaphragm
·Improved and optimized circuit and installation structure, enhancing vibration resistance and stability
·Large DIN connector, easy to install and use, high reliability.

6 Installation methods
⑴ Choose a place that is easy to operate and maintain for installation;
⑵ It should be installed as far away from the vibration source as possible;
⑶ Keep as far away from heat sources as possible;
It is best to connect the valve to the measuring pipeline;
During installation, use a wrench to clamp the six corners of the transmitter;
During operation, the connection between the Hirschmann joint and the housing cannot rotate.
