Input Level Gauge According to the measured liquid pressure, density, level of the three mathematical model relationship, through the level sensor and the level of liquid depth proportional to the level of pressure measurement, and after the signal processing circuit converted into a standard signal output, special gas-conducting cables, advanced process sealing technology and reliable special amplifier circuits and precision temperature compensation technology, so that the input level gauge has a high degree of accuracy, small size, good anti-leakage performance characteristics. It is characterized by high precision, small volume and good anti-leakage performance. Long-term immersion in the liquid work reliably and stably. Input level meter in the safe use of the process of attention to the following aspects: 1, the input level meter pressure inlet with isolation diaphragm, do not touch with foreign objects. 2, handling and installation of input level meter should be careful to avoid collision and affect the performance of the circuit. 3、During the installation of the input level meter, please do not use the wire to lift heavy objects other than the product. 4、Electrical connection, please strictly follow the wiring method, wiring errors will cause damage to the amplifier circuit. 5、Installation and use, if you encounter problems, please contact with the manufacturer of the input level meter, in the event of product anomalies, can not be opened for repair without authorization. 6, input level meter wire for the special waterproof wire, installation, use of the process should be eliminated wear and tear, puncture, scratch wire, if the scene of the above problems, the wire should take protective measures. The occurrence of such problems cause failure, need to re-purchase wire. 7、Input level meter probe is regularly dredged to avoid blockage of the pressure inlet.
