EGT 301, 401: Outdoor temperature sensor

Product catalog summary

Overview
The EGT 301 and 401 are outdoor temperature sensors designed to enhance energy efficiency by providing precise room temperature measurements for HVAC systems. These sensors are suitable for weather-dependent heating and ventilation systems.

Features

Available with passive or active measuring elements.
IP65 protection against dust and humidity.
Flexible cable inlet options.

Technical Data

Parameters: Recommended measurement current is less than 1 mA.
Time Constant: EGT*01F102: 12 min, EGT301F031: 7 min.
Ambient Conditions: Operating temperature ranges from -35 to 90°C for EGT*01F102 and -35 to 70°C for EGT301F031. Humidity tolerance is 85% rh.
Construction: Stainless steel sensor sleeve for EGT301F031, polyamide housing, and screw terminals for connections.

Standards and Directives

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

Resistance Values

Ni1000 and Pt1000 measuring elements with specific tolerances at 0°C.

Product Types

EGT301F102 and EGT401F102: Passive sensors with Ni1000 and Pt1000 elements, respectively.
EGT301F031: Active sensor with adjustable temperature ranges and 0-10 V output signal.

Description of Operation
The sensor's resistance changes with temperature, with a positive temperature coefficient. Elements can be exchanged within specified tolerances.

Areas of Use
Suitable for outdoor temperature measurement and use in refrigerated warehouses, greenhouses, and production facilities. EGT301F031 can be used in concrete ventilation ducts.

Intended Use
The product should be used as intended by the manufacturer, adhering to all related regulations. Modifications are not allowed.

Engineering and Fitting Notes

Designed for operation with safety extra low voltage (SELV/PELV).
Maintain constant ambient temperature for transducer electronics.
Installation should avoid direct exposure to rain and sunlight.

Connection Diagram
Includes details for connecting EGT301F102, EGT401F102, and EGT301F031 models.
