EXP-4PT Temperature Input :
It sounds like you're referring to a 4-channel Platinum temperature input module that works with PT100 sensors. PT100 sensors are commonly used in industrial applications for temperature measurement because they provide precise readings over a wide temperature range.
Here's a breakdown of what the model you're referring to might involve:
4 Channel: This module is capable of accepting input from four separate PT100 temperature sensors, allowing it to measure the temperature from multiple points simultaneously.
Platinum Temperature Input: The PT100 is a type of resistance temperature detector (RTD) that uses platinum as its sensing element. PT100 sensors have a resistance of 100 ohms at 0°C, and this resistance increases with temperature, providing a precise and linear way to measure temperature.
Type PT100 3 Wire (100 Ohm): PT100 sensors are available in different configurations, and the "3-wire" version is commonly used to minimize the effect of lead resistance. The three wires are typically connected to the RTD to improve measurement accuracy over long distances. The "100 Ohm" specification indicates the nominal resistance of the sensor at 0°C.
This module might be used in industrial systems for temperature monitoring, process control, or other scientific applications that require precise temperature readings.
