Note: for special requirements, please contact the manufacturer.
1.Please note that the tested medium shall be compatible with the part contacting the product and the medium.
2.When the transmitter with zero pressure and negative pressure is required, please indicate the range when ordering.
3.For special requirements, please consult with our company and indicate in the order.
PPM-T9201 series intelligent economy PPM-T9201 explosion-proof intelligent wireless pressure transmitter can be directly installed on the hydraulic pipeline through the pressure pipe joint.In critical applications (such as severe vibration or shock), pressure pipe joints can be mechanically decoupled by means of micro hoses.If the micro hose is used for installation, the shell must be grounded separately.When the instrument is connected to the power supply, it shall operate according to the electrical connection. After confirming that the operation is correct, it can be connected to the power supply for operation.Do not apply force to the instrument housing when removing the instrument.It is not allowed to replace components or structures, so as not to affect the explosion-proof performance.It is recommended to replace the compression seal ring regularly to ensure reliable operation of the transmitter.
