Issue

How to select a platinum sensor compatible with the Analog Input (AI) object in WorkPlace Tech.

Environment

WorkPlace Tech

I/A Series Lon (MNL) controllers

I/A Series BACnet (MNB) controllers

Cause

Sensor manufacturers provide platinum sensors with different Temperature Coefficient of Resistance (TCR).

Resolution

The Analog Input (AI) object supports 1Kohm platinum sensor with Temperature Coefficient of Resistance (TCR) equal to 0.00385 OHM/OHM @ °C.

Check manufacturer's datasheet and select sensor with TCR of  0.00385 OHM/OHM @ °C
