MAT01 Magnetic
angle transmitter
Magnetic electron transmitter MAT01, patent product,
a creation in the world .
Brief introduction
Built-in magnetic detecting electron module can precisely
measure the variation of surrounding magnetic field,
showing it in display board of calibration program in
the form of magnetic angle. By means of software calculation,
the variation of magnetic field can be transmitted into
a standard 4-20mA current signal output.
Features
* With built-in intelligent microprocessor in transmitter,
easy to layout and install 2-wire low consumption external
devices
* With transducer automatic gain controller
* 4-20mA analog current signal output, power supply:
24V DC
* Adjustable response speed to ensure stable analog
signal output
* Simple and versatile PC interface, common Windows
95/98 calibrating program for easy installation and
calibration (external power supply is not required).
* Accuracy of transmitter is more than 0.5% (range of
magnetic angle: 0.0 ~ 180.0)
Mainboard of flowmeter
with Hart function (Fig. 8)
Brief introduction
Mainboard of flowmeter with Hart function is a new
kind of digital flow transmitter with Hart communication
function. It can configure on site to display instantaneous
or total flow on large screen of LCD.

Features:
* Configurate by hand-held communicator or configuration
software of PC
* 4 - 20 mA output with HART protocol digital communication
(two wires)
* Communication meets HART protocol standard
* HART communication does not affect 4 - 20mA analog
output
* Power supply of HART transmitter: 12 - 36 V DC
* Damping: 0 - 32s adjustable
* Ambient temperature: -20 - +70≧
Wiring
Open the front cover of indicator, a blue connecting
terminal on top of the base (Fig. 9) can be seen,
then carry out wiring according to wiring marks on
terminal.

Meter adjustment on site
Flowmeter mainboard has two kinds of function modes:
data setting mode and current minitrimming mode.
* Data setting mode can set configuration data, flowmeter
data and reset accumulated flow into zero.
* Current minitrimming mode can minitrim 4mA and 20mA
current ( Need to equip with communicator of manufacturer).
