Overview
TANWELL flow switches HFS-T-R-S-B-T1, DTA3100, DTA3200, DTA3300 reflect changes in fluid flow rate by measuring the difference in resistance between these two thermistors. Wear resistant thermal flow sensors can be used for monitoring the flow rate of liquid or gas media. High cost-effectiveness. The displacement monitor is a four channel monitor. It can accept signals output by non-contact sensors and use these signals to drive alarms.
Product Details
Functional Principle
Plug in flow sensors are based on the thermal principle. The measuring probe heats up by comparing with the temperature of the fluid medium, and when the fluid passes through the probe, it takes away some of the heat. The change in fluid flow rate is reflected by measuring the difference in resistance between these two thermistors. Turck wear-resistant thermal flow sensors can be used for flow rate monitoring of liquid or gas media.

Flow monitoring is a program that requires reliable and repeatable monitoring of limit values and flow states. Flow sensors can detect key deviations in the flow velocity of liquid and gas media. Typical applications include monitoring cooling circuits during welding (such as preventing pump idling) and monitoring flow in ducts and air conditioning equipment. Due to the use of thermal principles, sensors can also monitor the temperature of the medium.
