2.6.0 Temperature Ratings
The maximum ambient temperature rating of the JLT series electronics is -40 to + 160° F. The ambient
temperature range of the LED readout is -10 to +160° F. Ambient temperatures above and below that
rating may cause the LED readout to malfunction. The transmitter head may require protection from
prolonged direct sunlight exposure. Low temperature cryogenic or high temperature insulation blankets
should be installed during extreme process operating temperatures.
The maximum process temperature rating of the JLT series transmitter is -40°F to +235° F and applies
to the waveguide probe.
2.7.0 Pressure Ratings
The maximum process pressure rating of the JLT series transmitter waveguide probe is 300 PSIG.
This rating applies to LGT-6000 series which is a direct insertion model for level gage applications only.
The waveguide probe in the ILT-6000 series transmitter is protected by and contained within the
thermowell and is therefore not subject to process pressure. The MGT-6000 is an externally mounted
transmitter and is not subject to process pressure.
2.8.0 Voltage
The JLT transmitter is designed to operate at 24 Volts DC, nominal.
Please ensure that the power
supply to the transmitter is the same 24 VDC voltage required. Although the voltage range of the JLT
transmitter is +12 to +30 VDC, it is highly recommended that the service voltage is established at a
stable and continuous 24 VDC. Higher voltages will damage the transmitter.
Do not connect to AC
current since this will damage the transmitter and violate the transmitter warranty.
