Questions & Answers

What are some adavantages of this device? (1 answer)
by Matt Mattigofen, almost 2 years ago
The TMR31 temperature sensor is quite small, compact and easy to commission. It is a 4-wire PC programmable transmitter with a 4-20 mA output offering great accuracies and short response times. Even with short insertion lengths, the device offers good precision. It is provided with the ReadWin 2000 PC operating software for configuration and visualization of the measured variable free of cost. Lastly, the enclosure protection of highest rating-IP69K is also an added advantage for the device.

What is the input given and its measuring range? (1 answer)
by Charles Henderson, over 2 years ago
The device takes the input of an Resistance Temperature Detector (RTD), a Pt100 type sensor (Platinum RTD) with a resistance of 100 ohms at zero degrees Celsius which changes with the change in temperatures. The Pt100 sensor as pet the IEC 60751, has a measuring range of -50 to +150 degrees Celsius (without neck) and -50 to +200 degrees Celsius (with neck).

Does it come with a display? (1 answer)
by Emory Crawford, over 2 years ago
The device doesn't have a display or a human interface. There aren't any display elements present directly on it, however the measured value and other required parameters can be called up using the ReadWin 2000 Software.
