Intelligent Sensors

sensorProbeX+ is compatible with all AKCP Intelligent sensors, making it an extremely versatile and cost effective monitoring solution. From the data center, to remote sites, industrial controls it has you covered.

Environmental Monitoring Sensors

Wherever monitoring of environmental conditions is important to your daily operations and health of equipment, deploy sensors to monitor temperature, humidity, airflow and water leaks.

Security Sensors

RFID Access control swing handle cabinet locks, door contacts and motion detectors will keep you in tune with the security situation at your sites down to cabinet level. Control who can access and when with RFID access control, centrally managed and monitored through AKCPro Server.

Power Sensors

AC Voltage detection, DC volt meters, sensor controlled relays and power metering can all be done on the SPX+

Specialized Sensors

Tank depth pressure sensors can monitor for liquid levels in fuel tanks, oil storage, chemical tanks and so on. Any tank up to 2 meters in depth can be monitored. Alarms generated when levels drop to critical levels, making sure you can re-fill with sufficient notice. Other specialized sensors include the keyswitch override, to disable notifications while maintenance work is being performed, and a programmable LCD display.

SPX+ Modules

The below modules can be added to the standard configurations to build up the device with what you need. For example, if you wish to have 12 sensor ports, you can order an SPX8 and an additional sensor4 module. You can also build your unit using our online configuration tool to check that it fits in 1U or 0U rack mounting. If you exceed 1U then there is the option to continue the configuration on an additional U connected via BEB to the base unit.

sensor4 Additional sensor ports can be added to the base SPX+ module in blocks of 4. sensor4 modules are compatible with all AKCP intellligent sensors. Build a cost effective monitoring platform, able to monitor multiple cabinets from a single IP address. Module Code :- S
Dry10/20 Dry contact modules come in several flavors. IO modules, and isolated input only.

sensorProbeX+ Expansion Architecture

Every SPX+ comes with both EXP (Expansion) and BEB (Basic Expansion Bus) ports. These expansion ports give you the ability to add functionality to your base device, so your system can grow with your needs.

Basic Expansion Bus (BEB)

BEB is suitable for short distance expansion within your cabinet. Build up your system adding additional SPX+ BEB Remote units. Daisychain the expansion units up to a maximum of 20 meters for the total chain. SPX+ BEB Remote units are cost effective expansion when you place the unit within the same or neighbouring cabinet.

4x BEB – Max total cable length 10 meters

3x BEB – Max total cable length 18 meters (3x 6m)

2x BEB – Max total length 20 meters (2x 10m)
