Temperature Sensors for the medium air and liquid


Serie TD4A

This serie is designed for measuring temperatures in liquids. The sensor has two pins. The anodized aluminium case with external thread protects the sensor and assures simple mounting. The entirely waterproof case is convenient for mounting in basins. However, it is not designated for complete immersion. The typical response time (time constant) equates to medium air (inactive) about 4 minutes, in medium water 15 seconds, only (values refer to unmounted condition).

Short description: liquid level temperature sensor, length 38,1mm, external thread 3/8-24 UNF-2A, anodized aluminium case, 2 black teflon-isolated leads with length152mm.

Serie TD5A

Remarkable for these precision sensors is the small miniature design (TO-92 case). This series has 3 pins, the pin in the middle is not connected. The typical response time is 11 seconds in moved air and 30 seconds in inactive air.

General information

Very accurate, +/-0.7°C at 23°C ambient temperature, sensor element consists of one silicium chip 0,04×0,05” with a thin film resistor network, the sensor element is laser-trimmed, 2000 Ohm at 23°C, working temperature from -40°C to + 150°C.

Typical applications

Ambient temperature monitoring, motor temperature monitoring, control circuits, automotive, air and oil temperature monitoring.
