Wind pressure sensor for automatic ventilation equipment of power system in power plant

  Ptj-gh / ghx-501 / 501f / 501zf / 501-1 / 501-1f / 501-1zf gas differential pressure sensor, micro differential pressure sensing controller Haojie electronic micro differential pressure sensor characteristics: ptj-ghx series is a new sensing controller newly developed by Gaoming Haojie, which is referred to as sensor controller for short
This series mainly uses the sensing core and is processed by the multi loop operational amplifier circuit developed by duogao minghaojie, which can directly achieve the purpose of control
In general occasions, it can replace frequency conversion and PLC, Display the cumbersome operation process of the control instrument Play the purpose of direct control
1: contact with the measured point is made of ABS, which is firm and durable
2: The self-developed amplification circuit is adopted to greatly improve the stability of sensor signal output
3: flexible multi action output, range control, single point control and analog signal synchronous output mode, so that the field application is simple and clear
4: GH improves the audible and visual alarm function, so that the user can clearly understand whether the current situation has achieved the desired purpose GHX four digit display high-precision display and control panel 5: the adjustment range can be set arbitrarily within the sensing range selected by the user
6: the core sensing core adopts imported silicon piezoresistive core, so that the sensor can carry out high-quality sensing under micro pressure Application: widely used in environmental protection, energy saving, ventilation, fire protection, air conditioning and other fields It is used for fan automatic control, ventilation pipe, leakage detection, liquid level, high negative pressure and other micro pressures, which should be measured and controlled with high precision
