INSTRUCTION MANUAL
1. Attention on handling
...
・The application medium of this product is corrosive gases/liquids compatible with SUS304.
・Never insert any foreign matters, like wire or needle, into the pressure port hole. It causes the breakdown.
・Do not apply exceeding the maximum pressure as shown in the specification. The excessive pressure may affect the sensor characteristics and
may make accurate measurement impossible.
・Do not give unnecessary force to the main body and cable when installing the product. The excessive pressure may affect the sensor characteris-
tics and may make accurate measurement impossible.
・Be sure to connect the output terminals correctly. Wrong connection will cause damage of the internal electric circuit.
・Please supply a stable power source and do not exceed the specified supply voltage. It will cause damage of the electric circuit.
・Please make a high-pressure side the same as the piping condition on a low-pressure side when you lay pipes.（Diameter and length of the
tube etc.）When a transitional pressure fluctuation is caused, it causes the breakdown if the condition is not the same.
・This product is dust proof and drip proof（to IP65 of IEC standards）and is not suitable for use in environments requiring higher standards.
・Please supply a stable power source.
・Place the wiring as far away as possible from the power lines carrying large power. The output becomes unstable because of the noise etc.
