The CRESSTO M - miniature pressure transmitter are designed for measuring both relative overpressure and underpressure in liquid and gas media of a non-aggressive character. The nominal pressure range ± 50Pa to ± 300kPa, supply voltage of 5 to 15 VDC, supply current of 0.5mA and an operating temperature range of -15 to +85°C.
The unit accompanies a protection class of IP54. The unit can be additionally equipped with a pressure snubber. The sensor requires no maintenance during operation and corrections are made ??by the manufacturer. The casing is made from duralumin with elox coating. The connecting thread measures about M12x1.5. The measured media comes into contact with silicon, duralumin, silicon rubber, plastic and polyetherimid.
Electric connection is mass-realized by a miniature sealed arrested connector according to DIN 43650C. The cable bushing size is PG7 and dimensions measure up to 6.5mm. It is possible to deliver transmitters with a cable outlet made to a special order. The pressure sensor consists of a silicon membrane with a semi-conductor scanning resistors and the transmitter is adjusted by means of thin-layer resistors.
