【UE H400-S134B H402-S134B】U.S. UE switch original double point switch 2*SPDT U.S. UE 400 series pressure switch overview 400 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 H400 series main models and features H400 type, single-point output, internally adjustable, Model H402 with reference scale , dual-point output, internally adjustable, type H403 with reference scale, three-point output, internally adjustable, with reference scale H400-S134B Parameters: Contact form 1*SPDT Wetted material 316L stainless steel bellows pressure Interface 1/2NPT inner wire Electrical interface 3/4NPT inner wire Action range -1~1.4bar Pressure resistance 1.7bar H402-S134B Parameters: Contact form 2*SPDT Liquid contact material 316L stainless steel bellows Pressure interface 1/2NPT inner wire Electrical interface 3/4NPT inner wire Action range -1~1.4bar Pressure resistance 1.7bar H403-S134B Parameters: Contact form 3*SPDT Liquid contact material 316L stainless steel bellows Pressure interface 1/2NPT inner wire Electrical interface 3/4NPT Wire action range -1~1.4bar, pressure resistance 1.7bar 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 through the connecting rod Push the switch connector to connect or disconnect, 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 generates Displacement, push the switch element directly or after comparison, change the on-off state of the switch element, and 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. related terms Accuracy: A value indicating the degree of precision of the device, including linearity, tolerance, hysteresis, repeatability, etc. At present, the highest precision of Nagano's pressure switch can reach ±0.5%FS, and the model is CB33. Maximum pressure (Max.P): the maximum value of the pressure range. Full Scale (FS): The difference between the maximum and minimum values ​​of the pressure range. Connection difference (dead zone): It refers to the difference between the switch setting action value and the reset value. For example, when the set value is 1MPa and the actual reset value is 0.9MPa, the connection difference is 0.1MPa. Working temperature: refers to the temperature range in which the internal mechanism and sensitive components of the instrument will not undergo continuous deformation during operation. Generally, the recommended operating temperature range of the pressure switch is -5~400C. If the temperature of the medium is too high, it can be considered to add an accessory siphon (filling shape) to achieve the purpose of cooling. SPDT (Single Pole Double Throw): Consists of a normally open, a normally closed contact and a common terminal. DPDT (Double Pole Double Throw): It consists of a symmetrical left and right common terminal, and two sets of normally open and normally closed terminals. Upper limit one contact (normally open): When the pressure rises to the set value, the contact will act and the circuit will be turned on. Lower limit one contact (normally closed): When the pressure drops to the set value, the contact will act and the circuit will be turned on. 0140 Gold contacts M201 factory setting, need to specify the rising or falling setting The M277 nameplate uses kPa or MPa as the pressure range unit, factory selected. not suitable for temperature switches M278 uses kg/cm2 as the pressure unit on the nameplate, not applicable to temperature switches M405 complies with European ATEX intrinsically safe standards M406 complies with the Russian Gosgortechnadzor flameproof intrinsically safe standard M421 explosion-proof junction box, only suitable for Russian explosion-proof standards M423 ATEX Compliant Flameproof Junction Box M430 Lid lock M444 Paper Signs M446 stainless steel tag M460 external grounding screw; for non-metallic piping systems (ATEX installations) M480 differential pressure switch type K, 316 stainless steel pressure port, sensor material cannot be changed.
