Sensors and Field Instruments

An abundance of remote sensors are connected to the industrial control management infrastructure. These sensors collect and communicate process and environmental information back to the automation controllers. Within the wide range of sensor types used, the most common are temperature, pressure, and vibration. Standard outputs used for communications include analog voltage or current, smart digital, and digital on/off (in the case of threshold sensors).

Field instruments are handheld devices that are frequently used to maintain, repair, and calibrate remote sensors. These devices are typically battery powered and require precise sensor interface electronics.

RTD-to-Digital Temperature Sensor Interface


Provides 0.5°C total accuracy with fault detection and ±45V input protection

4V to 42V, 100mA, Compact Step-Down Power Module


The MAXM17532 is a step-down DC-DC power module built in a compact uSLICTM package. The MAXM17532 integrates a controller, MOSFETs, an inductor, as well as the compensation components. The device operates from an input voltage of 4.0V to 42V, supports an adjustable output voltage from 0.9V to 5.5V, and supplies up to 100mA of load current. The high level of integration significantly reduces design complexity, manufacturing risks and offers a true “plug and play” power supply solution, hence reducing the time-to-market.
