1. INTRODUCTION
This Manual is intended for users of smart temperature transmitters type
LI-24
– in normal and intrinsic-
safety versions.
The data and information for the intrinsically safe
LI-24
transmitter are given at point 5 „
Use of the LI-24
transmitter in danger zones
”.
The data and parameters specified in other points of the Manual are common for both versions, and several
differences relate to electrical supply have been taken into the text.
2. APPLICATIONS AND MAIN FEATURES
The rail-mounted smart temperature transmitters
LI-24
are designed to
resistance and voltage
conversion in 4
– 20mA measuring signal with Hart communication. Transmitters have two
measuring canals which carry through measuring difference, middle, middle with redundancy,
minimum and maximum of temperature. Transmitters are factory compensated from ambient
temperature effect and have compensation possibility of thermocouple cold lead ends with inside
or offside sensors.
The
LI-24
transmitter features:
a)
Two-
wire power supply (4…20mA current loop),
b)
Digital signal processing (filtration, linearization, compensation),
c)
Transmitter configuration possibility (with Hart Protocol) as sensor type, calibration, programming
and range difference, user measuring profile enabling.
d)
Autodiagnostic system
e)
Ability to cooperate with resistive and thermocouple sensors, (see table 1 and 2)
f)
Ambient temperature effect compensation
g)
Input/output galvanic separation.
3. CONSIGNMENT CONTENTS
