2 The change in the output voltage ofthe bridge is proportional to the Pressure and can be measured 135 with PNP switch outputThe process Pressure acting on the metallic separating diaphragm of the sensor istransmitted to a resistance bridge via a fill fluid. A differential amplifier creates astandard signal from the Pressure -proportional change in the output voltage of thebridge. A comparator with an adjustable hysteresis compares this signal with thepre-set switch point and then activates the transistor output and LED T PMP 135 Pressure Transmitter with: 4 to 20 mA analog outputPower supply, RN 221N Transmitter power supply unit from Endress+Hauser Switch outputPreferably in connection with a programmable logic controller (PLC). Positivesignal at electronics switch (PNP).Measuring systemInputThe measured variable for the cerabar T PMP 135 Pressure Transmitter can beselected as either gauge or absolute ranges up to 500 psi (40 bar) can be selected (refer to Ordering Informa-tion).
