MultiMux Multiplexer
In stock
Over-Voltage Protection (OVP) on all instrument channels
Low contact resistance relays provide compatibility with a wide range of instruments, including vibrating wire, resistance strain gage, thermocouples, linear potentiometers and 4-20mA, among others.
Two control inputs provide for activating the MultiMux and then advancing through the channels. Logic levels for either the enable or clocking input can utilize 5V to 12V logic input, with a maximum input of 16V. The control inputs are compatible with a wide variety of control modules including those manufactured by Campbell Scientific, Sutron and Datataker. Contact Canary Systems® for MCU support from other manufacturers.
MiniMux Multiplexer
In stock
The MiniMux is designed to expand the number of instruments that can be read by a compatible Automatic Data Acquisition System (ADAS). It supports two switching modes, 16 channel by 4-wire switching, or 32 channel by 2-wire switching. An easily accessible board mounted switch configures the switching mode.

MLMux5 Multiplexer
In stock
The Canary Systems® MLMux5 multiplexer is designed to expand the number of instruments that can be read by a compatible Automatic Data Acquisition System (ADAS). It supports two switching modes, 5-channel by 4-wire switching, or 10-channel by 2-wire switching. A switch on the face of the module configures the switching mode.
The use of low contact resistance relays means almost universal instrument support, a high degree of lightning protection on the control lines, and virtually infinite channel isolation. The MLMux5 is compatible with a wide range of instruments, including vibrating wire, resistance strain gage, thermocouples, linear potentiometers, and 4-20 mA, among others.
VW Comm Interface Module
In stock
Three industry standard communication interfaces are included: RS-232, RS-485 and SDI-12. The RS-232 interface provides compatibility with a wide range of standard wireless adaptors and modems including those from Digi International and Freewave, facilitating the deployment of cost-effective networks of wireless sensors.
The RS-485 interface allows an inexpensive, reliable wired network to be built using simple twisted pair cabling. Up to 61 nodes are supported in a wired network, with up to 1200m (4000’) of cabling. The network can be easily extended with RS-485 repeaters.
The vibrating wire interface consists of a precision differential amplifier with band-pass filtering, which improves noise rejection and measurement reliability. The excitation and measurement parameters are programmable to support all commonly used vibrating wire instruments. Reading output can be programmed for digits (Hz^2×10–³), frequency (Hz) or period (μS).
CABLES
In stock
Braided cable is used to ensure maximum protection and CE compliance for EMC; PUR provides excellent abrasion resistance and flexibility and LSHF (low smoke halogen free) cables are designed for increased safety in the case of fire and used extensively in underground applications. All cables are compliant with the RoHS Directive 2002/95/EC.
Vented cables are also available for use with vented transducers to allow for atmospheric compensation and armoured cables for use in applications such as dams.
TERMINAL SWITCH BOX
In stock
Switching box used to group multiple sensors in a single location providing a convenient mean of taking
readings.
The Switching box consists of a fiberglass enclosure containing terminal blocks, rotary switches, cable input connectors
and sockets for portable readout connection.
The switching box can handle up to thirty two 4-conductor sensors, and allows lightning protection to be added for
each of these conductors.
The Switching box can be used all types of VW sensors & increases efficiency of taking of manual readings.
The Switching box may be fitted with a multiplexer for use with a CR6 data acquisition system.
