EGT 311, 411: Clamp-on temperature sensor

Product catalog summary

Overview: The EGT 311 and 411 are clamp-on temperature sensors designed for precise room temperature measurement, enhancing energy efficiency in HVAC systems. They are suitable for monitoring energy consumption and controlling HVAC installations.

Features:

Available with passive or active measuring elements.
IP65 protection against dust and humidity.
Designed for temperature measurement on pipes with diameters ranging from 10 to 50 mm.
Includes a retaining strap and silicone-free heat-conducting paste.

Technical Data:

Recommended measurement current is typically less than 1 mA.
Time constant with heat-conducting paste is 16 seconds.
Storage and transport temperature range: -35 to 70 °C.
Humidity tolerance: 85% relative humidity, non-condensing.
Housing made of polyamide, available in yellow/black.
Connection terminals support 0.35 - 1.5 mm² wires.

Standards and Directives:

IP65 protection as per EN 60529.
CE conformity according to RoHS Directive 2011/65/EU and EMC Directive 2004/108/EC.

Resistance Values:

Ni1000: 1000 Ω at 0 °C, ±0.4 K tolerance.
Ni200: 200 Ω at 0 °C, ±0.4 K tolerance.
Pt100: 100 Ω at 0 °C, ±0.3 K tolerance.

Product Types:

EGT311F022: Passive, Ni200, -35 to 90 °C, 80 g.
EGT311F102: Passive, Ni1000, -35 to 90 °C, 80 g.
EGT411F102: Passive, Pt1000, -35 to 90 °C, 80 g.
EGT311F031: Active, adjustable range -50 to 160 °C, 0...10 V output, 120 g.

Operation: The sensor's resistance changes with temperature, with a positive temperature coefficient. It is designed for use on pipes and curved surfaces, connecting to control and display systems.

Installation Notes:

Requires safety extra low voltage (SELV/PELV) for operation.
Must be installed by a qualified electrician.
Use retaining strap for fitting, ensuring the tube diameter does not exceed 50 mm.
Apply heat-conducting paste to the brass sleeve before fastening.

Disposal: Follow local laws for product disposal. Additional material information is available in the product's environmental declaration.

Product data sheet Accessories Type Description 0300360002 Retaining strap 900 mm and heat-conducting paste 0300360004 Heat-conducting paste incl. gun with 2 g content Description of operation The resistance of the measuring element changes according to the temperature. The temperature coefficient is positive, which means the resistance increases along with the temperature. The elements can be exchanged within the specified tolerance ranges. Areas of use Clamp-on sensor for temperature measurement on pipes and curved surfaces. Designed for connection to control and display systems. Intended...
