Simple Remote Sensor Monitoring for PLC's & Automation Systems


The Industrial Ethernet Node (IE-NODE) is a remote monitoring interface designed to provide sensor data to PLC’s or other automation and control systems.

Both units can be expanded to 16 sensor inputs with the installation of optional expansion boards.

The IE-NODE operates by reading its sensor inputs and sending processed data when requested by another system (e.g. PLC). The units are equipped with an RJ45 Ethernet socket and supports PROFINET, EtherNet/IP and Modbus TCP/IP protocols for easy integration with Siemens, Allen-Bradley Rockwell, Modicon and other PLC’s or automation devices.

The IE-NODE’s network configurator software provides a visual view of all devices on the network. It allows for easy identification of each unit on the network and allows for network settings to be changed as needed.

Mill-Speed Switch

Milli-Speed Switch

The Milli-Speed switch sensor with 4-20 mA linear output signal is designed to detect belt slip, belt underspeed, stop motion, low speed or zero speed on bucket elevators, conveyors, air locks, mixers, fans, grinders and many other rotating machines. Totally sealed and simple to calibrate, the Milli-Speed works in the harshest of conditions.

More Info

P800 Proximity Switch

P800 Inductive Proximity Sensor

The P800 Proxswitch is an inductive sensor designed to detect shaft speed, shaft position, gate position, or object presence.

More Info

  Whirligig Sensor Mount  

Whirligig® - Shaft Sensor Mount

The Whirligig is a fully guarded target for easy mounting of motion sensors like the P800 Proxswitch.  The Whirligig is available with 1, 2, 4 or 8 pulse targets, and attaches to the machines shaft by a 1/2 in. tapped hole or magnetically using the Mag-Con™ adapter.

More Info

SpeedMaster Speed Switch Tester

SpeedMaster™ Speed Switch Tester

The SpeedMaster™ with Pulse Pilot is the only device that accurately tests the calibration of a speed switch, and allows testing of the alarm and shutdown features of the sensor while installed on the machine shaft.

More Info

 Touchswitch Belt Misalignment Sensor

Belt Misalignment Sensor (Contact)

The Touchswitch™ is an electromechanical limit-switch with no moving parts, which detects tracking and misalignment problems on bucket elevators and conveyors. Unlike a rub block that utilizes friction (heat) to activate, the Touchswitch is pressure sensitive (contact) for safer and more reliable monitoring.

More Info

  Brass Rub Blocks  

Belt Misalignment Sensor (Temperature)

Brass rub blocks process temperature information.  When the belt from a bucket elevator or conveyor rubs against the brass block, heat is created from the friction which is then relayed to a temperature sensor generating an alarm.

More Info

Bearing Temperature Sensor

NTC Bearing Temperature Sensor

The ADB series have been designed to allow the depth of the sensor to be adjustable.  They screw directly into a bearing housing through the existing grease zerk thread.  Each sensor is fitted with a grease zerk to allow lubrication of the bearing without the need for removal of the sensor.

More Info

P800 Proximity Switch

Milli-Temp Bearing Sensor

The Milli-Temp series can be used on any application where bearing temperature monitoring is needed. The Milli-Temp is a loop powered analog sensor with a 4-20 mA linear output that is scaled across a temperature range for continuous temperature monitoring.

More Info

ADB Bearing Sensor Tester

ADB Bearing Sensor Tester

The ADB Sensor Tester has been designed to test 4B adjustable depth bearing (ADB) temperature sensors in the field.  During planned maintenance or periodic testing, this diagnostic tool to verify the alarm and shutdown sequences of the control unit are functioning as expected.

More Info

Surface Temp Sensor

Surface Temperature Sensor

The WDB7 bolts directly onto a bearing housing, motor, gearbox, or machine casing for continuous temperature monitoring.

More Info

Binswitch Plug/Choke Sensor

Plug / Choke Sensor

The Binswitch Elite detects level or plug situations for bulk granular solids or liquids in tanks, bins, or silos and can be used as a plug or choke detector in chutes, conveyors and elevator legs.
