A. Product Overview

The Autonics T4WM-N3NP0C Digital Temperature Indicator is designed to monitor temperature from up to five separate Pt100 temperature sensors using a single panel mounted instrument.

Instead of installing an individual temperature indicator for every measurement point, the T4WM-N3NP0C allows multiple temperature points to be connected to one device. The operator can view each channel individually using manual channel selection or allow the indicator to automatically cycle through the connected temperature channels.

This makes the model particularly useful for industrial applications where several parts of a machine, process, tank, chamber, or system need to be monitored.

B. Working Principle

The Autonics T4WM-N3NP0C works by receiving resistance signals from Pt100 RTD temperature sensors installed at different measurement points.

A Pt100 sensor changes its electrical resistance according to temperature. The temperature indicator measures this resistance and converts it into a corresponding temperature value.

The basic working sequence is:

1. Up to five Pt100 sensors are installed at different temperature measurement points.

2. Each sensor is connected to a separate input channel of the T4WM-N3NP0C.

3. The indicator reads the resistance signal from the selected Pt100 sensor.

4. The resistance value is converted into a temperature value.

5. The measured temperature appears on the digital LED display.

6. The indicator can then move to the next channel automatically or according to manual channel selection.

7. This process continues across the connected measurement points.

Example

Consider a machine with five different temperature measurement locations:

• Channel 1: Inlet temperature

• Channel 2: Process chamber temperature

• Channel 3: Heater temperature

• Channel 4: Product temperature

• Channel 5: Outlet temperature

Five Pt100 sensors can be connected to the T4WM-N3NP0C.

The operator can then monitor all five temperatures from a single display instead of installing five separate temperature indicators.

C. Why Is Autonics T4WM-N3NP0C Used?

The Autonics T4WM-N3NP0C 5 channel temperature indicator is used when temperature must be measured at several locations but only one centralized display is required.

It can reduce the number of individual indicators required in a control panel and provide operators with a simple way to monitor multiple temperature points.

Main Reasons for Using It

• Monitor up to five temperature points

• Use five Pt100 sensors with one indicator

• Reduce control panel space

• Reduce the number of separate display instruments

• Provide centralized temperature monitoring

• Automatically scan different temperature channels

• Allow manual temperature channel selection

• Provide clear digital temperature indication

• Monitor industrial processes from one panel location

Common Applications

The T4WM-N3NP0C can be suitable for:

• Industrial ovens

• Heating systems

• Process tanks

• Drying equipment

• Manufacturing machines

• Packaging machinery

• Food processing equipment

• Pharmaceutical equipment

• HVAC systems

• Industrial control panels

• Test benches

• Research equipment

• Temperature monitoring panels

• Process machinery

• Production lines

• Heat treatment equipment

• Water systems

• Machine temperature monitoring

• Multi zone temperature monitoring

• Industrial process monitoring

Example Industrial Application

Consider an industrial drying machine with five different sections.

A Pt100 sensor can be installed in each section. All five sensors can then be connected to one T4WM-N3NP0C.

The operator can monitor the temperature of each section from a single panel display and identify whether one area is operating at a significantly different temperature from the others.
