MPM4809TD Level Transmitter
Introduction
MPM4809TD Level Transmitter is a submersible piezoresistive
level measuring instrument with all seal construction. High stable
and reliable piezoresistive pressure sensor and high-precision
circuit chosen. Whole temperature range of digital temperature
compensation is done. Specialized cable is sealed with the
housing. The air vented tube is inside of the cable. MPM4809TD
can be used for a long time in the liquid that is compatible with
transmitter housing material.
MPM4809TD Level Transmitter is small in size, light in weight,
good stability in long term use. Customers do not need to adjust
themselves. It can be used for level measurement and control in
oil, chemical industry, medicine, metallurgy, power plant, mine, city
water drainage and hydrology.

Note:
① Testing is under normal temperature (refer to 20℃ ± 5℃ );
non-linearity. Accuracy is rms root-mean-square of non-linearity,
repeatability, hysteresis.
② Within the temperature range, it includes total index of non-linearity,
repeatability, hysteresis, zero drift, sensitivity drift, zero short-term
stability etc.

Notes
1.Measured media should be compatible with
transmitter material, and the density of the measured
media should be clearly indicated (except water).
2. It uses Polyurethane cable.
3. Cable length is as per the requirement of clients.
4. If clients has special requirement, please contact us.
