Universal pressure transmitter transmitter output 4-20mA; threaded connection M20 * 1.5; field LED display pressure value; accuracy of 0.25; pressure type gauge pressure (zero and the atmosphere connected), measuring range 0-1MPa.

Seven, use and installation

1. Pressure transmitter should be installed as far as possible in places where temperature fluctuations, while avoiding vibration and shock.

2. Process connection: M20 * 1.5 because of different working conditions, and NPT, ZG, R, G and other threaded interface and HG, ANSI and other specifications flange interface (before ordering the user to consult with our company).

3. Transmitter for a variety of mild corrosive liquid and gas pressure measurement. Produced by the explosion-proof requirements of the transmitter, according to the product explosion-proof grade for different explosive environments, and its associated equipment should have the explosion-proof function.

4. For strong corrosive media (such as acid, alkali) and other corrosive media, can choose diaphragm technology diaphragm pressure transmitter for the scene.

5. Signal terminals are OUT + and -. TEST + and - for the field signal test terminal, with a multimeter 20mA block positive and negative gauge pen measurement.For the anti-interference, the signal line and other power lines not through the line pipe or trunking, High-power equipment through the vicinity,

6. It should be noted that strong corrosive or superheated media should not be in direct contact with the transmitter, such as the use of lead pressure pipe, should prevent the sediment in the pressure tube precipitation, and in the measurement of steam or other high-temperature medium, Transmitter operating temperature exceeds the limit for steam measurement, the pressure pipe to be filled with water, to prevent direct contact with the transmitter and steam.

8, pressure transmitter safety instructions

1. Non-explosion-proof power supply must pass through the safety barrier The maximum open-circuit voltage of the transmitter is less than 35V and the maximum short-circuit current should be less than 35mA.

2. When the transmitter is composed of a circuit, the sum of the resistances shall be within the working area specified in the operating instructions. When the explosive environment is used, the total amount of bus inductance is less than 1 m H and the total distributed capacitance is less than O. 1 uf.

3. After wiring the lid must be tightened by hand, threading hole must be sealed to prevent the shell of water.
