Sensorex Smart Sensors

Skip the Transmitter. Take sensor outputs directly to your PLC.

Simplify Installation No Transmitter Required
Sensorex Smart Sensors are a robust, small footprint solution: great for saving space in a panel. These versatile sensors feature open protocol digital (MODBUS) communications or analog (4-20mA), giving you the flexibility to build customized systems without being locked in to one manufacturer’s instrumentation.

Increased Confidence in Your Readings Modbus data provides diagnostics
MODBUS enabled smart sensors can store valuable data, like the part number and date of manufacture, making this information more readily available. Output calibration history and impedance values can be output, providing sensor health diagnostics.

Quick Configuration Free Sensorex Software
Sensorex Smart Sensors are easy to configure using our free software. They can be pre-calibrated at your facility, eliminating the need to calibrate in the field.
Complete Modular Sensors
Modular smart sensors are a perfect solution for quick replacements! Sensor cartridge, electrode holder, electronics module, and cable assembly are all individually replaceable saving costs when the sensors or other module comes to end of life. Sensorex offers modular sensors in pH/ORP and contacting conductivity. Integrated sensors are easy to install and replace at end of life.
