JOHNSON CONTROLS TE-635AM-2 Platinum Temperature Sensor, Well Mounting

Johnson Controls temperature sensors of TE-6300 line are ideal for diverse temperature sensing needs in building automation systems and direct digital control systems. Johnson Controls TE-635AM-2 temperature sensor is used in wall mount, well insertion, strap mount, duct probe & averaging and outdoor air applications. Johnson Controls TE-635AM-2 is available in a package with the required mounting accessories for ease of installation and reduced commissioning time & cost. Users can check out Johnson Controls temperature sensors page on or website for more variants of this sensor.

Working Mechanism:

• Select a proper mounting location without direct sunlight, radiant heat, excessive vibration or electrical noise.
• Insert the sensor probe of Johnson Controls TE-635AM-2 temperature sensor into a thermowell up to 1/8 inches (3 mm) from the bottom and then tighten the thermowell's set screw.
• Wire the sensor to a controller. Users can use multiple sensors (of the same type) in series / parallel wiring arrangements for average temperature reading in a large area or duct.
• Keep the electrical wiring as short as possible to reduce wire resistance induced temperature error.
• Reposition the cover of the enclosure and tighten the cover screws. Now the temperature sensor is ready for operation.
• The temperature sensor measures the change in resistance due to temperature change in the media and indicate an accurate temperature reading.

Features:

• Johnson Controls TE-635AM-2 thin-film platinum type, temperature sensor has 1k ohms sensor reference resistance at 32 degrees F (0 degrees C).
• It can be operated at temperatures ranging from -50 to 220 degrees F.
• This TE-635AM-2 sensor has a 6 inch (152 mm) long probe that can be directly mounted on a thermowell for quick installation.
• It comes with a corrosion-protected steel enclosure for covering the connections and preventing accidental disconnection or error.
• This sensor has an accuracy of +/-0.35 degrees F at 70 degrees F.
• It connects to 14 to 22 AWG connections using wire clamps.

Compatible Accessories:

• TE-6300W-101 & TE-6300W-102 Thermowells: They come with thermal grease for direct mounting of the 6 inch probe of TE-635AM-2 temperature sensor without using an external adaptor. These thermowells have stainless steel or brass with copper bulb construction for corrosion resistance.

Standards and Approvals:

• Meets UL 1995 plenum use requirements

Frequently Asked Questions:

Q. What are the uses of thermal compounds in thermowells?

A. Thermal compounds like thermal grease or paste are used to fill the air gap between a temperature sensor & thermowell walls. These compounds improve stability and provide accurate temperature readings.

Q. How does a temperature sensor work?

A. The temperature sensors work on the principle that the temperature change cause change in the electrical resistance of a material. Temperature sensors are made of a wide variety of materials for varying accuracy & application requirements. The change in electrical resistance results in voltage change that can be measured by a controller for indicating temperature readings.
