Terminal and Junction Boxes
Datasheet
Terminal boxes are used for projects that require the integration of cables from multiple instruments into one convenient location.
A terminal box consists of a fibreglass or diecast aluminium enclosure with a variety of size and switching options.
Product Features
- Terminates Vibrating Wire, thermistors and two- or four-wire type instruments
- Standard Junction/Terminal Boxes (switching and non-switching) cater for 12, 24 or 48 instruments
- Small Terminal Box (non-switching) connects up to 5 separate instruments
Product Benefits
- Ideal solution for terminating multiple cables
- Allows joining of several individual cables into a single multicore cable
- Provides convenient access for readings
- Provides protection from water ingress and corrosion resistance
Operation
There are several options available:
Small Terminal Box – Non-switching
These small terminal boxes are used to take a reading of between one and five Vibrating Wire instruments (including their integral thermistor) using one of itmsoils VW Readouts. The instrument cable from each individual Vibrating Wire sensor enters the terminal box via a sealing cable gland and is connected to a terminal block. There is a pre-made connection between the terminal block and a circular connector for use with itmsoils readout.
Terminal Box – Switching
Switched terminal box enclosures are made of fibreglass reinforced polyester. The enclosure comes complete with a hinged lid, cable entry glands and internal termination board. They are used to take manual readings of multiple instruments using a single readout connection point and a rotary switch.
There is a standard allowance of 12, 24 or 48 instruments.
Junction Boxes – Non-switching
These enclosures are made of fibreglass reinforced polyester.
The enclosure comes complete with a hinged lid, cable entry glands and internal termination board. They are used to join or extend cables en route to a terminal box or datalogger; it is common to take multiple cables into one multicore cable.
There is a standard allowance of 12, 24 or 48 instruments.
Junction Boxes – Switching
Switched junction boxes allow multiple cables to be integrated into a single multicore cable, as well as offering the option to take manual readings. The manual readings are taken using a single readout connection point and a rotary switch. There is a standard allowance of 12, 24 or 48 instruments.
