Installing a Remote Sensor Junction Box

Sensors mounted remotely must use the ULTIMA X5000 or JB 5000 junction box. Only one sensor can be connected to each junction box. The junction box housing is the same construction as the ULTIMA X5000 transmitter. The mounting options and instructions for connecting the sensor are the same for sensors connected directly to the ULTIMA X5000 transmitter housing. The junction box is available in 316 Stainless Steel.

Sensors can be remoted up to 328 ft (100 m) from the transmitter housing, as long as the ULTIMA X5000 transmitter is mounted within maximum distance from the power supply, as indicated in tables in Sensor Mounting. The junction box does not have an illuminated display and has two connectors: a single sensor input and an output connecting to the transmitter. A 16 AWG (1.31mm2) 4 element cable with a braided shield should be used for the electrical connection between the junction box and the ULTIMA X5000 transmitter. Specific cable recommendations are Alpha wire 3248 or equivalent.

The X5000 junction box or JB5000 must be used for remote mounted sensors. The use of third party junction boxes may void product warranty.

If the remote sensor is not easily accessed, it is best practice to install tubing that can be used to apply calibration gas from the device display. Route the tubing to the ULTIMA X5000 Gas Monitor, ensuring that there are no kinks, leaks or other obstructions. Secure this tubing near the monitor.
