4.Remote Mount Electronics Option. Due to process temperature, vibration or accessibility the housing/electronics of the LTM transmitter can be remote mounted as far as 25 ft. The housing/electronics are supplied with a pipe- mount bracket that can be mounted most nearby posts or pipes with hose clamps. The drawing below depicts a gage mounted transmitter in the top mount remote electronics configuration.

electronics configuration.

NEVER install the sensor probe inside an insulation blanket that may be around the level gage. This will overheat the sensor probe and cause failure.

NEVER bend, bow or cause a kink in the sensor probe, this will damage the instrument and void the warranty. Do not attempt to straighten the sensor probe, this will not help the instrument work. If the shipment arrives damaged please file a claim with the shipping company and contact the factory to arrange for a replacement.

There are a variety of ways to install a standalone transmitters (i.e. crane, lift, etc…), the basic rule to remember when installing an LTM transmitter is DO NOT DAMAGE the sensor probe, this will void the warranty. If damage is suspected please contact the factory and be prepared to provide pictures.

In REMOTE MOUNT electronic options please support the sensor probe at the elbow/condulet and then every 3 feet (depending on length of cable). Support at every 2 feet may be required if explosion proof conduit is utilized by the end user.
