Resistor Modules

Resistor Modules are designed to emulate the use of resistive sensors in variable resistors in systems when testing devices such as engine controller. Find out more about the technical background to Pickering Interfaces Resistor Modules from this page

Importance of Thermoelectric EMF in resistor simulators
Thermoelectric EMF can cause errors in the simulation of resistors, particularly when the measuring system uses low voltages. This page describes the effects of Thermoelectric EMF's on these measurements. Pickering Interfaces Precision Resistor family minimizes errors form these sources by ensuring the switch design has low thermoelectric EMF
