PPM-T9101 Intelligent Economical Medium And High Pressure Wireless
Pressure Transmitter
Products Description
PPM-T9101 series intelligent and economical wireless pressure
transmitter is a high-energy lithium battery powered pressure
detection intelligent instrument with wireless communication
function.The instrument adopts a 24 bit high-precision AD converter
to collect pressure and temperature signals, which realizes the
zero point and temperature performance compensation of the
transmitter in a wide temperature range.The core adopts silicon
micro melting process, which 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
human-machine interface adopts 0.96 inch low-power LCD screen,
which is easy to operate and display.The main application fields
are fire control, water supply, heating, industrial monitoring
system, etc.Through the way of wireless communication, the
long-distance wireless transmission of signal is realized, which
simplifies the installation mode, saves the wiring cost of
customers, and truly achieves the purpose of energy saving and
environmental protection

Installation Instructions
PPM-T9101 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.When the measuring range is less than 100KPA, it must
be installed vertically. If it is installed with micro hose, the
shell must be grounded separately.Do not apply force to the
instrument housing when removing the instrument.
