PPM-T9204 Explosion Proof Wireless Level Transmitter
Description
PPM-T9204 intelligent wireless liquid level transmitter is a high
energy lithium battery powered, intelligent instrument for liquid
level detection with wireless communication function. the
instrument uses silicon piezoresistance with stainless steel
isolation film as the pressure signal measuring element, pressure
and temperature signals are collected by 24-bit high-precision ADC,
the zero point and temperature performance compensation of the
transmitter in a wide temperature range are realized. support a
variety of wireless, 433,LORA,LORAWAN,GPRS,LTE,NB-IOT,WIFI etc. .
the man-machine interface uses a 1.3-inch low-power LCD screen,
operation display is convenient for application. the field of
application is liquid level monitoring in the field or in the
situation where the supporting power supply environment is
inconvenient, such as fire tanks, pools, wells, etc. , by means of
wireless communication, for long-distance wireless transmission of
signals, this simplifies the installation, it saves the wiring cost
of the customers, really achieve the goal of energy conservation
and environmental protection.

Installation Guide
PPM-T9204 intelligent wireless level transmitter probe can be
installed with flange bracket, the display can be installed with a
sheet metal bracket. when removing the instrument, do not apply
force to instrument case.regular replacement of pressure seal ring
is recommended, to make sure the transmitter works properly.
