The HD3604T... and HD36V4T... are pressure transmitters with microprocessor and current ( 4...20mA) or voltage ( 0...5V, 1...5V or 0...10V) output, respectively. The sensor, piezoresistive, is insulated and allows gas and liquid pressure measurement over a wide range of temperatures. The measured pressure is relative to atmosphere. The different models cover the scales from 6 to 600bar. The case is in stainless steel diam. 20mm and encloses sensor and electronics: in order to connect it to a pressurized system, it is supplied with a ¼ â BSP threaded connection with a 22mm hex fastening ring. For electrical connections, three different solutions are provided: ⢠A male connector DIN 43650A, ⢠A male connector DIN 43650C, ⢠A circular male connector DIN 41524. The connectors are fitted with a three or four pole free female socket with fairlead ( according to the models) . All transmitters are factory calibrated at three points. The use of a microprocessor circuit allows memorizing the sensor response curve and correcting any possible non linearity. No calibration is required by the user.
