Model ETT-10V Vibrating Wire Temperature Sensor

ETT-10V temperature sensor is designed for measurement of internal temperature in concrete structures, soil or water. It consists of a magnetic, high tensile strength stretched wire fixed to a material with different co-efficient of linear expansion. Any change in temperature directly affects the tension in the wire and thus its natural frequency of vibration.

Specifications:
Range	- 20° C to 80° C
Accuracy	± 0.5 % fs normal
Enclosure	± 1 % fs optional Stainless steel, IP 68 hermetically sealed by electron beam welding

Model ETT-10TH Resistance Thermistor Probe

ETT-10TH is designed for measurement of surface temperature of steel and concrete structures and bulk temperature inside concrete. It can also work submerged under water. ETT-10TH is a low mass water proof temperature probe. Due to its low thermal mass it has a fast response time

Specifications:
Sensor type	R-T curve matched NTC thermistor, equivalent to YSI 44005,
Range	- 20° to 80° C
Accuracy	1° C
Body material	Tin plated copper

Model ETT-10PT RTD Temperature Probe

ETT-10PT can be used in similar applications as ETT-10TH. The probe has excellent stability and accuracy that makes it well suited for long-term installations where high accuracy and reliability is required. It consists of a ceramic resistance element (Pt 100) with DIN IEC 751 (formerly DIN 43760) European curve calibration. The resistance element is housed in a closed-end robust stainless steel tubing that protects the element against moisture.

Specifications:
Sensor type	Pt 100
Range	- 20° to 80° C
Accuracy	± (0.3° C + 0.005 ltl)° C
Calibration	DIN IEC 751
Curve (European)	a = 0.00385 Ohms/Ohm/° C
