Data Harvest Voltage Sensor ±20V – Model 3160 [2519]

The Data Harvest Voltage Sensor ±20V is a versatile, classroom‑ready sensor designed to measure potential difference across electrical components in both DC and low‑voltage AC circuits. With its wide ±20 V measurement range, this sensor is ideal for more advanced circuit investigations while remaining safe and appropriate for school laboratory use.

This model is part of a complete range of four Data Harvest voltage sensors, each covering a different voltage range to suit a variety of experimental requirements. The ±20V version is particularly useful where higher voltages are required for demonstrations, allowing students to explore realistic electrical systems without compromising accuracy.

When connected to Data Harvest data logging systems, the sensor provides real‑time voltage measurements that can be displayed graphically, recorded digitally, and analysed in detail—helping students link practical observations directly to theoretical understanding.
