5. DESCRIPTION
5.1. Area of application
The 8400 threshold detector / transmitter is used to measure the
temperature of a liquid or a gas.
The threshold detector can be used to control a valve or activate
an alarm. A transmitter version can also be used to establish a
control loop.
5.2. General description
5.2.1. Construction
The threshold detector / temperature transmitter is made of
an electronic module and a measuring element. The electronic
module can be adjusted by 180°.
• The electrical connection of the 8400 threshold detector is
made via an M12, 5-pin fixed male adjustable connector and,
depending on the version, an EN 175301-803 fixed connector.
• The electrical connection of the 8400 transmitter is made via
an EN 175301-803 fixed connector and an M12, 8-pin fixed
male connector.
The 8400 requires a 12...30 V DC power supply.
• Depending on the version, a threshold detector has 1 NPN or
PNP transistor output or 1 relay output.
• A transmitter has 1 4...20 mA current input, 1 4...20 mA current
output and 1 relay output.
