1. This products have wide applications in engine,compressors, chillers, air –conditioners, automobiles, gas and oil fields, water-supply, project machines, hydraulic systems and so on.

2. 0-5V;0-10V;0.5 to 4.5V is standard output, which is amplified signal, means it has better stability and long-distance transmission ability, quick response.

3. small volume easy to fix in some cramped space. Easy operation and fitting.

4. Needs to be connected with indicators or PLC etc., to read out the pressure value., you can consider our indicator PI600 serious.

5. Regular cleaning and checking is necessary.

6. If there is high temperature environment, performance will be influenced more or less, which we called temperature shift.

7. 0.5-4.5V is available, which is widely used in automobile field.

8. life time over 100,000,000 pressure cycle.

9. If there is no reflection after you fitting please check in main two steps:

Is wire connection right ?    Use amperometer to check.
