PPM-T9201 Explosion Proof Medium And High Pressure Wireless Pressure Transmitter
Description
PPM-T9201 explosion-proof medium and high voltage wireless pressure transmitter is a high-energy lithium battery powered pressure detection intelligent instrument with wireless communication function.The instrument uses the micro melting pressure sensor as the pressure signal measuring element, and uses 24 bit high-precision AD converter to collect the pressure and temperature signals, so as to realize the zero point and temperature performance compensation of the transmitter in a wide temperature range.It is characterized by stainless steel single piece integrated structure, no O-ring, no weld, no silicone oil, wide pressure range, adaptability to harsh environment, wide range coverage, and strong overload capacity.Support a variety of wireless: 433, Lora, lorawan, GPRS, LTE, nbiot, WiFi, etc.The man-machine interface adopts a 1.3-inch low-power LCD screen, which is easy to operate and display.The application fields are natural gas, petrochemical industry, fire control, tap water, industrial monitoring system, etc. through wireless communication, the signal remote wireless transmission is realized, thus simplifying the installation mode, saving the wiring cost of customers, and truly achieving the purpose of energy conservation and environmental protection.
PPM-T9201 explosion-proof medium and high pressure wireless pressure transmitter, the product technical conditions and verification methods conform to gb3836.1-2010 "explosive environment Part 1 General requirements for equipment" and gb3836.2-2010 "explosive environment Part 2 equipment protected by flameproof enclosure" d ".
PPM-T9201 explosion-proof medium and high pressure wireless pressure transmitter has passed the examination of explosion-proof product inspection organization designated by the state and issued "explosion proof certificate", with explosion-proof mark Exd Ⅱ C T6 GB.

Installation Guide
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.
