800 Series Electronic Indicating Pressure Transmitter/Switch

The Noshok 800 Series Pressure Transmitter/Switch is used for the switching of circuits as a function of the measured pressure. In addition, the pressure value can be output to appropriate read-out units as a standardized analog signal. The switching conditions can be programmed directly at the pressure transmitter/switch (switch and reset points,etc.). Via the different display elements, switching statuses and pressure values can be read.
