Remote SmartMux

The Remote SmartMux is a modular multiplexer that allows the management of multiple sensors as part of a remote or automatic data acquisition system. It is an easy-to-use digital alternative to the traditional vibrating wire rotary switch terminal box.

Sensor connection is simple thanks to plug-in connectors. Sensor channels can be easily viewed and selected via the SmartMux Interface which replaces time-consuming rotary switches and readout. It is connected into one central location with subsequent connection to a data logger via one multi-core cable. The cost of cabling and installation is therefore significantly reduced.

It is available either as an analogue or digital version and can be used with a wide range of sensor outputs including VW, V, mV/V, 4-20mA, Pt100, NTC and RS485. Models are available as 4, 8, 12, and 16 channel and can be configured either as 2 pole (2 wires) or 4 pole (4/3 wires) or any combination of each.

Example: 16 channel can have 32 x VW or 16 x VW + Temp or any combination.

The Remote SmartMux is powered from a GeoLogger module for cable lengths up to 1000 metres. For lengths greater than this an additional power source will be required within the Remote SmartMux, which can be battery or solar powered.

The amount of multiplexers required will depend on the number of sensors within each location.
