High-performance eddy-current sensors consist of an electronics module and probe which is connected to the module by a cable. These systems are available in different configurations and price points.
The ECL202 Eddy-Current Sensor is our best eddy-current product. Digital technology brings the highest linearity, resolution, and temperature stability. A setpoint switched output allows you to monitor a process and trigger an action when needed. The offset and and setpoint threshold are set with push-button controls. The module can be operated with other ECL202 modules and has the option of a rear connector DIN rail bus for multiple modules.
The ECL150 Eddy-Current Sensor is a high-performing eddy-current displacement sensor. It uses the same digital technology that brings the highest linearity, resolution, and temperature stability. The sensor offers up to eight channels in a compact space, perfect for embedded applications requiring high resolution and linearity.
The ECL101 is based on analog circuitry and features good performance in both linearity and resolution. The ECL101 can achieve bandwidths as high as 80 kHz,making it an excellent choice for high-frequency applications. It includes a screw-adjust offset and voltage and current outputs.
The ECA101 is a lower cost eddy-current sensor. The output is nonlinear, but the sensor includes a set point switch which can monitor a process and call for action when the process reaches a critical point. It has screw-adjust offset and gain controls so you can optimize this sensor in your application for the best possible performance at a lower cost.
The ECA110 is an OEM version of ECA101 for embedded systems. Each PCB is custom designed with your components for your calibrations and requires minimum quantity orders. There are no user adjustments or indicators making it perfect for embedded systems where the sensor is out of sight.
