TANWELL sensor

TANWELL sensorSK081T-070-50，SK205-050-H020，SK081T-110-500， The change in fluid flow rate is reflected 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 non-contact sensor outputs, enabling it to calculate more than 14 key parameters for each channel. The module includes a built-in relay (expandable to five) and two 4-20mA outputs.

The BENTLY 330750 design in the United States separates the speed probe from the signal processing circuit and connects it with a sturdy cable, allowing the speed probe to have a much wider temperature range than our other Velomitor sensors.

BENTLY 190501 from the United States is our low-frequency Velomitor sensor used for monitoring cooling towers with rotation speeds as low as 90 rpm

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.
