Micro pore water pressure sensor use matters needing attention

Micro pore water pressure sensor use matters needing attention：

    1. Correctly connect the wiring according to the wiring requirements. If there is no signal output when the connection is reversed, the transmitter can work after the power is turned on, but the output signal is more stable and reliable after 30 minutes warm-up. 2. To improve the anti-jamming capability, the shielded cable should be Connected with monitoring and control instrument shielded wire or earth; 3. The transmitter is used in medium that is not corrosive to silicon and stainless steel (except special anti-corrosion); 4. The maximum pressure of the measured system can not exceed 120% of rated value. The pressure end of the transmitter must not be connected to conductive, corrosive liquids or gases. The air guide holes of the liquid level sealed air guide cable must not be blocked. 5. Do not press the silicon chip with a sharp, hard object. 6. If necessary The user can open the upper cover of the transmitter during the calibration test, fine-tune the zero (Z) and full-scale (S) potentiometers (except the waterproof seal type); 7. The signal amplifier is not waterproof, and the water inlet will damage the circuit board; 8 Each sensor corresponds to its signal amplifier. Different sensors and amplifiers cannot be interchanged.
