TA Temperature Sensor - Airmar T80 (8-pin)

The Airmar T80 sensor is designed to measure air or water temperature. Its versatility allows it to be used in various applications, whether for ambient temperature or liquid temperature.

The Airmar T80 temperature sensor housing is made of stainless steel. This material ensures good durability and compatibility with various hull types, including aluminum, provided it is properly isolated.

The Airmar T80 transducer comes with a 9-metre (30-foot) cable. This length provides flexibility during installation and routing to the compatible instrument.

The Airmar T80 sensor is equipped with an 8-pin (8G) connector. This connector is designed for direct integration with compatible Garmin devices.

The T80 sensor features a thermistor with a nominal resistance of 10,000 ohms at 25 °C (77 °F). This specification is critical for accurate temperature measurements.

The Airmar T80 sensor provides a temperature accuracy of ±2°C over a range of 0 °C to 30 °C (32 °F to 86 °F). This accuracy ensures reliable readings within the specified operating range.

The Airmar T80 sensor is designed to operate within a temperature range of 0 °C to 30 °C (32 °F to 86 °F). This is the range in which the specified accuracy is guaranteed.

The Airmar T80 sensor weighs approximately 0.2 kg (0.5 lb). This lightweight design makes it easy to install on various surfaces.

The T80 and T25 are both standalone temperature sensors. The main difference lies in their design and application:

The T80 features a stainless steel housing, can measure air or water temperature, and is designed for surface mounting. The T25 is optimized for air temperature with a plastic housing and has a very fast thermal response time in air.

The T80 and T42 sensors are standalone temperature sensors with distinct designs:

The T80 features a stainless steel housing, is designed to measure air or water temperature, and is surface-mounted. The T42 is a through-hull bronze model, specifically designed to measure water temperature on fiberglass or wooden hulls.

The Airmar T80 sensor is a surface-mount model and can be installed in various locations depending on the intended application:

On the transom for water temperature measurement.In a livewell.In the engine compartment for other temperature measurement applications.If measuring water temperature, choose a location where the sensor will be constantly in contact with the water.

When installing the T80 transducer on a metal hull (such as aluminum), it is essential to isolate the stainless-steel transducer housing from the metal hull. Use appropriate marine sealant to prevent electrolytic corrosion. It is also critical never to install a metal transducer on a vessel with a positive ground system.

To install the T80 transducer, you will need the following tools and materials:

Safety glasses, dust mask, hearing protection.Pencil.Electric drill.Bits: 3 mm (1/8") for pilot holes. An 18 mm (3/4") bit may be required for a through-hole in the transom (if applicable).2 stainless steel self-tapping screws 4 x 18 mm or #8 x 3/4".Marine sealant (suitable for below the waterline).Screwdriver.Cable ties (to secure the cable).Cable gland (to protect the cable during routing).

For pilot holes to secure the T80 transducer, use a 3 mm (1/8") drill bit and drill to a depth of 10 mm (3/8").

To route the T80 sensor cable:

Run the cable to the instrument without tearing the outer jacket. Use cable glands to reduce friction. Keep the sensor cable separate from other electrical wiring and noise sources to minimize interference. Coil excess cable and secure it with cable ties to prevent damage.

It is strongly recommended not to remove the connector from the cable to facilitate routing. If the cable must be cut and spliced, the Airmar No. 33-035 waterproof junction box must be used, and the provided instructions must be followed to maintain installation integrity.

After launching the boat, immediately check for leaks around the screws and any other holes drilled in the hull where the sensor was installed. This ensures a watertight and secure installation.

Yes, the T80 sensor can be installed below the waterline, particularly on the transom for water temperature measurement. However, it is essential to ensure it remains in constant contact with the water for accurate readings and to check waterproofing after installation.

Yes, the Airmar T80 transducer, with its stainless steel housing, is compatible with all hull materials. For metal hulls, such as aluminum, it is crucial to isolate the transducer from the hull using marine sealant to prevent electrolytic corrosion.

The Airmar T80 sensor features an 8-pin (8G) connector and is designed for direct integration with compatible Garmin devices equipped with an 8-pin input port for temperature sensors.
