Original HM5406A hydraulic pressure sensor

Product description

Pressure transmitters and pressure sensors are used in industrial equipment to ensure proper operation and accurate measurement. It is necessary to maintain and calibrate the sensor regularly. Usually, the pressure guide is removed before calibration, but this is troublesome. In applications, when the Pressure Transmitter and Pressure Sensor are connected to the pressure conduit, it is usually necessary to remove the connector of the pressure conduit, pressure transmitter and pressure sensor and then connect it to the pressure source for calibration. But the operation is cumbersome, cumbersome, time-consuming and a waste of manpower. Before disassembling and assembling, we also need to worry about the joints. Standard commonly used pressure transmitters and pressure sensors, regardless of whether the pressure guide pipe will break or leak, the positive and negative pressure chambers are equipped with exhaust valves, drainage valves or cocks; This allows me to easily calibrate the pressure transmitter and pressure sensor in the field, i.e. without removing the pressure conduit. The method is as follows: first close the positive and negative valves of the three valve groups, open the balance valve, then release the exhaust valve, drainage valve or cock for exhaust, and then replace the exhaust valve, drainage valve or cock connected to the positive pressure chamber with a self-made joint; The negative pressure chamber is connected to the loose state so that it is open to the atmosphere. Connect the pressure source with the homemade connector through the rubber hose, close the balance valve, check the tightness of the gas path, and then connect the manual operator of the ammeter (voltmeter) to the output circuit of the transmitter, and start calibration after charging and preheating. Specializing in the manufacture of intake manifold absolute pressure sensor, common Rail Pressure Sensor, hydraulic pressure sensor, injection molding machine special pressure sensor, Urea Pressure Sensor, Brake Pressure Sensor, etc.
