Digital sensor output

Because of the wide range of the sensors, only four different sensor units are needed to cover the entire range of dp spans from 100 kN/m2 to 20 MN/m2 (4 in water to 3000 lb/in2) An internal temperature sensor monitors the temperature of the pressure sensor and is used to compensate the sensor output for the effects of temperature changes. The sensor temperature may also be transmitted digitally for monitoring, alarming, and for other appropriate applications. 

The challenge to meet industrial requirements is the necessity to decouple external mounting forces and internal clamping forces from the transducer in a small available space. This is a precondition for good performance and long-term stability. The digital pressure output signal is conditioned to adjust sensitivity and to compensate for thermal effects. A precision of 0.5% of the sensor s full scale (30 bar) and a resolution of 2 mbar can be achieved. 

Digital input/output terminals are the basis for cooperation of sensor and data acquisition cards. A typical process of cooperation is to start the measurement of an external instrument by a digital trigger puke from... 

A multichannel electronic interface device (eg, data-logger) that reads the sensor output, converts it to a digital signal and sends it to a computer. 

The device was operated at a constant drain-source current and voltage. The measurement was carried out with a feedback loop by regulating the reference voltage. The sensor output signals in terms of gate voltage shift were measured as a function of the DO concentration by a digital voltmeter. 

The output of the sensor system delivers a digital signal- The sensor is supplied with 5VDC via a coded RAST 2.5 plug connection. The sensor consists of water resistant material and is therefore especially suitable for the use in household appliances Like dishwashers or washing machines.
