Installing the DIN Rail Mount Transmitter
Example
4.2.4
Distance from sensor
The maximum cable length between the sensor and the transmitter is 1000 ft (300 m).
Micro Motion supplies 4-wire cable to connect the sensor to the transmitter. The cable is fitted with a
®
Eurofast
connector for connection to the sensor. Cable can be ordered in lengths ranging from 6.5 ft
(2 m) to 500 ft (150 m). For longer cable lengths, contact the factory.
4.2.5
Accessibility for maintenance
Ensure that the transmitter is mounted in a location that will allow easy access to the terminals and the
front panel.
4.3
Mounting and removing the transmitter
The transmitter is designed to be mounted on a 35 mm rail. The DIN rail must be grounded. See
Figure A-3 for dimensions.
If the temperature is above 113 °F (45 °C) and you are mounting multiple transmitters, they must be
mounted at least 0.33 in (8,5 mm) apart. Use an end bracket or end stop to space the transmitters. See
Figure 4-2.

LF-Series Flowmeters: Sensor/Transmitter Installation
The transmitter is mounted 350 feet from a DC power supply. If you want to use
16 AWG cable, calculate the required voltage at the DC power supply as follows:
