2.0 OVERVIEW

2.1 Storage and Handling Information

If possible, storage prior to installation should be indoors at ambient temperature, not to exceed the following:
Temperature range: -40 to 150 degrees F.
Humidity: 0 to 100% R.H. non-condensing.
To avoid probe damage:
Do not transport or support the weight of the MT5000 by means of the probe.
Installation of rigid probes and flange mounted transmitters may require the use of lifting equipment.
Avoid sharp bending of cable probes which can result in poor instrument operation.
The lids on the MT5000 housing are sealed with o-rings. To avoid damage to the electronics, both lids should be
closed tightly before and after installation.

2.2 Ambient Temperature

The MT5000 electronics temperature may not exceed 170°F / 77°C. For higher ambient temperatures due to radiant
process heat, a high temperature extension option is required. The coupler process temperature shall not exceed
the temperature stated in the datasheet specifications for the given coupler.
2.3 Description & Principle of Operation
The MT5000 is a 4-20mA loop powered Smart Level Transmitter, which is microprocessor based and is available
®
with HART communication. It uses very low power microwave energy to determine the level of the product being
measured. In order to obtain optimum performance, it is important to understand the basic principle of operation. The
electronics housing is typically fitted with a special adapter ―Coupler‖ serving as a process connection and seal, and
holding a solid rod or a cable. The rod or cable ―Probe‖ hangs into the vessel and acts as a wave-guide, i.e. the
microwave energy stays concentrated around the probe and along its length, instead of being dispersed in a cone,
as it would be if there was no probe.
