Air Temperature Measurement Sensor
The rugged temperature sensor is specifically designed for outdoor air temperature measurement in demanding environments. It is well-suited for arduous applications where durability and reliability are essential. The sensor is available with or without a protective shroud, and it can be surface-mounted using housing options such as ABS, aluminium, or stainless steel.
Depending on the specific requirements, the PPL10 air temperature measurement sensor can be configured with a terminal block or a transmitter for data transmission. It supports Type J, K, or T thermocouple sensors, allowing for accurate temperature measurements in the operating range of -40 to 85°C.
The sheath material is housed in a short 316 stainless steel probe, ensuring resistance to corrosion, with an optional radiation shield. This is fitted with your choice of housing suitable for fixing a wall or surface wherever necessary. We can offer aluminium, ABS or stainless steel versions to fit your application. All of our housings are rated to at least IP67 ingress protection.
We can also fit a number of options inside the terminal housing that best fit your requirements. The simplest is a terminal block allowing you to connect directly to the sensor. Alternatively, we can supply temperature transmitters with either a 4-20mA or a 0-10V output.
The temperature sensor adheres to the tolerance band standards of BS EN 60584-2:1993, offering precise temperature readings with Class 1 or Class 2 accuracy. It supports simplex or duplex wiring systems, providing flexibility in installation. The thermocouple sensor can be manufactured according to specific requirements, accommodating industrial needs and individual preferences.

FAQs about Thermocouple Ambient Air Sensors
Can Thermocouple Measure Air Temperature?
Yes, a thermocouple can measure air temperature. A thermocouple is a type of temperature sensor that operates based on the principle of the Seebeck effect. It consists of two different metal wires joined at one end to form a junction. When this junction is exposed to a temperature gradient, it generates a voltage proportional to the temperature difference.
By measuring this voltage, the air temperature can be determined. To measure air temperature accurately, the thermocouple needs to be positioned appropriately in the airflow, ensuring it is not affected by external factors such as radiation or convection that could impact the readings.
How is Outside Temperature Measured?
Outside temperature is commonly measured using a device called a thermometer or a thermocouple air sensor. Thermometers can be based on various principles such as mercury, bimetallic, or electronic sensors. These devices are placed in outdoor locations away from direct sunlight and heat sources to provide accurate readings of the ambient air temperature.
How to Measure Room Temperature?
To measure room temperature, you can use a digital thermometer, a thermostat, or a temperature sensor. Place the device in the room away from direct heat sources or drafts, and let it stabilise for accurate readings. Ensure that the device is calibrated properly and follow the manufacturer’s instructions for precise measurement.
