TK-100TR-EX
Intrinsically Safe Dew Point Transmitter

The TK-100 Explosion-Proof Dew Point Transmitter is a capacitive dew point meter developed for measuring moisture in gases in explosive hazardous areas. The capacitive dew point meter uses a sensor element that detects changes in capacitance corresponding to the amount of moisture adsorbed.

This device is combined with an isolation barrier to create an intrinsically safe explosion-proof system, making it suitable for use in specially hazardous areas (formerly classified as Zone 0). The isolation barrier is installed in a non-hazardous area, with power supplied to the transmitter from a non-hazardous location.

The meter detects dew points in the range of -100°C to +20°C with an accuracy of ±2°C. The measurement results are output as an analog 4-20 mA signal and are used for dew point management in non-hazardous areas via the isolation barrier.

By handling all process from manufacturing and production lines to calibration in Japan, we place the highest priority on quality. We are committed to providing products at price range that is easy to introduce into various customer site conditions.
At the same time, we have established a system for quick delivery to meet your needs.

For the past 40 years, TEKHNE Corporation has been handling moisture management and measurement instruments, focusing on dew point meters. The capacitive (impedance) dew point meter TK-100 series is the explosion-proof version of our flagship product.
The TK-100 Explosion-Proof Dew Point Transmitter requires a combination with an isolation barrier, which is available as an optional accessory.

Sampling with the TK-100 Explosion-Proof model is very simple.
You can either install it directly in the duct or measurement environment, or if bypassing is possible, install the filter, sensor block, and flowmeter for sampling. These components are available as an optional “starter kit.”

To achieve highly accurate moisture measurement, it is essential to select the appropriate piping materials and equipment based on factors such as the type of measured gas, level of contamination, flow rate, pressure, and the desired dew point for measurement.
Typically, a sensor block is used for measurements. However, if the measured gas and environment are clean, the sensor unit is equipped with a 5/8 UNF connection thread, allowing it to be directly inserted into a duct by threading the connection.
