About
The Thermoelectric Converter DT 27 is a specialized sensor engineered for precise temperature measurement within liquid engines of rocket and space technology products. It is capable of measuring temperatures of both aggressive liquids like liquid oxygen and non-aggressive liquids and gases such as naphthyl. The converter boasts an extended temperature range from -196°C to +600°C and is flight-qualified, ensuring its reliability in demanding space environments. Key features include high reliability against vibration, shock, temperature fluctuations, and humidity. Its design incorporates special alloys, allowing it to maintain operability even when exposed to aggressive environments at temperatures up to 600°C. The DT 27 provides an analog output and features a robust design that ensures high vibration and shock resistance, particularly at the cable termination site. The converter consists of a sensitive element housed within a casing, a cable jumper, and a connector. The sensitive element is based on a thermocouple cable with mineral insulation, conforming to TU 16-505.757 standards.
