รุ่น SHP
คุณลักษณะ
This SHP has been designed for challenging tasks of measuring and control. It has a total error of typically 0.1% (max. 0.15%) under RT referential conditions. By means of a contact controlled by a solenoid, the zero point of a transmitter allows for subsequent adjustment in order to correct errors caused by drift or the installation position, for example. With the SHP-P version, various parameters of the transmitter can be altered by means of a handheld device or the PC. Apart from scaling the measuring range at a ratio of 4:1, it can also be shifted, which permits a transmitter of a nominal range of 0 to 10 bar to be set at a measuring range of 1 to 4 bar. Also the measuring rate and type of output filter, the characteristic curve (inverting, taking the root, or as a free characteristic curve on 11 nodes) and, in a wide range, the output signal can be adjusted. Its robust design guarantees a high level of reliability and safety, also in rugged conditions. Its stainless steel diaphragm is fully vacuum-tight, extremely burst-resistant and applicable with all standard media in hydraulics, pneumatics, etc., as long as they are compatible with stainless steel.

| IP system of protection | THE IP system of protection as specified in the data sheets generally applies, with their mating plud connected. Relative pressure transmitters usually require a centilated mating plug and/or cable to aloow for pressure comsation. From a pressure range of 60bar, a ventilated mating plug and/or cable is not necessarily required. | ||||
