Precautions for use
Warning!
！
The transmitter must be installed by professional technicians who read
and understand this operation manual.
！ Warning!
Do not measure media with incompatible materials in contact with the
transmitter.
DANGER!
！
This product is a non explosion-proof product. It is strictly
prohibited to use it in the explosion-proof area, otherwise it will
cause serious personal injury and material loss.
! No modifications or changes can be made on the equipment.
! Handle the transmitter with care and do not throw it at will. Do
not use brute force when installing the transmitter.
! This product belongs to weak current equipment, which must be laid
separately from strong current cables, and shall be wired in
accordance with relevant national wiring standards (GB / t50312-2016).
Ensure that the power supply voltage meets the power supply
requirements of the transmitter.
Prevent chemical reagent, oil and dust from directly invading the
sensor, and do not use it in the environment of condensation and
extreme temperature. Do not perform cold or heat shock.
The protective cover can be removed after 2 ~ 3 months of use,
and the filter screen can be cleaned to make the measurement
environment circulate normally.
Installation precautions
！ Warning!
The equipment must be installed without power supply.
If the transmitter is installed in a harsh site and will
encounter dangerous damage such as lightning stroke or overvoltage, we
recommend that the user carry out lightning stroke and overvoltage
protection between the distribution box or power supply and the
transmitter.
The installation height is the sitting height of the human body
or the environmental area mainly required to be measured.
The transmitter shall be placed vertically as far as possible.
During installation, ensure that the sensor is under the transmitter
(the font on the transmitter is positive).
It shall be installed in an area with stable environment, avoid
direct lighting, stay away from windows, air conditioning, heating and
other equipment, and avoid directly facing windows and doors.
The transmitter and conductor shall be far away from places with
high voltage and serious electromagnetic interference, and away from
high-power interference equipment as far as possible to avoid
inaccurate measurement, such as frequency converter, motor, etc.
Confirm whether the power supply voltage is correct, and the
positive and negative of the power supply correspond to the positive
and negative wiring of the product; Avoid installing in the position
easy to bump, so as not to damage the product.
Install
Wall installation
The back of the transmitter is equipped with a guide rail mounting
plate. Remove the mounting plate first. The accessories are equipped
with two wallboard self tapping screws and two plastic expansion
pipes. First punch two holes with diameter of 6mm and depth of ≥ 30mm
on the wall (please refer to the dimension drawing of guide rail
mounting plate for hole position). Insert the expansion pipe, fix the
guide rail mounting plate on the wall with self tapping screws, and
then slide in the transmitter.

directly into the DIN rail.
Key dialing description
The digital output temperature range is - 40 ~ 125 ℃, and the
corresponding output data is 0-1650. The temperature ranges of current
output and voltage output can be changed by dialing the key on the
dial switch on the internal circuit board. There are eight ranges to
choose from (as shown in the figure below). The factory default
temperature range is - 40 ~ 100 ℃.

Represents shielded wire, and all marked grounding points must
be effectively grounded. It is recommended to select shielded twisted
pair signal cable for the best effect. In order to avoid grounding loop,
the shielding layer adopts single end grounding, insulated floating
grounding at the transmitter end and grounding at the control cabinet end.
It is recommended to select cables with an outer diameter of
4 ~ 6mm to ensure the protection grade.
