H400-S126BUE开关可调范围（【H400-S126B】U.S. UE switch agency adjustable range with reference scale ）

【H400-S126B 】U.S. UE switch agency adjustable range with reference scale U.S. UE 400 series pressure switch overview400 series pressure, differential pressure and temperature switch is a switch with diverse uses, especially suitable for multi-point output and control . Two-point and three-point settings provide multi-point switch output, which can be used for alarm and shutdown, early warning and alarm, high/low limit and liquid level Tube pressure interface 1/2NPT inner wire Electrical interface 3/4NPT inner wire Action range -1~0bar Pressure resistance 0.3bar H402-S126B Parameters: contact form 2*SPDT liquid contact material 316L stainless steel bellows pressure interface 1/2NPT Wire electrical interface 3/4NPT inner wire action range -1~0bar pressure resistance 0.3bar H403-S126B parameters: contact form 3*SPDT liquid material 316L stainless steel bellows pressure interface 1/2NPT inner wire electrical interface 3/4NPT Wire action range -1~0bar Pressure resistance 0.3bar H400 series main models and features H400 type, single-point output, internally adjustable, with reference scale H402, double-point output, internally adjustable, with reference scale H403 type, three Point output, internally adjustable, with reference scale Working principle The working principle of the pressure switch: When the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor moves instantaneously, and the switch joint is pushed through the connecting rod On or off, when the pressure drops or rises to the rated recovery value, the disc resets instantaneously, and the switch automatically resets, or in simple terms, when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, directly Or push the switch element after comparison to change the on-off state of the switch element to achieve the purpose of controlling the measured pressure. The elastic components used in the pressure switch include single coil spring tube, diaphragm, bellows and so on.
