China Manufacturer 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.
