         TE-660 Transmitter without monitor

• Fast response time

Introduction

TE-660 Dew point transmitter with a measuring range down to -60°C dp is ideal for applications in compressed air systems, plastic dryers and industrial drying processes. An integrated auto-calibration procedure permits a measurement accuracy of <2 °Cdp.

The measured values for dew point is available on an analog 4-20 mA. Integration into the measurement task is simplified by the compact design and the exceptionally robust stainless steel housing.

Application

• Monitoring of compressed air systems

            refrigerant type dryer

            absorption dryer

            plastics dryer

• Semiconductor
• Industrial Furnace
• Battery Predictor

Installing

If installing directly into the process, a stop valve should be at both sides of the installation point. This makes it easy to remove the transmitter for maintenance and calibration.

Monitor for TE-660 On-line

If power supply and display are required, TK-100 On-line monitor is included in TK-660 On-line.
