Our PR-25AP RTD Air Probe combines the availability of the high accuracy sensor options found in our Ultra-Precise RTD probes with the convenience and reliability of our M12 enabled PR-21 probes. The PR-25AP offers RTD accuracies of Class A, AA (formerly 1/3DIN) and 1/10DIN sensing elements with the ease and reliability of the M12 connection.
The PR-25AP RTD is also designed to provide a barrier to airflow between the air stream and the ambient conditions that has been tested to 400 psi with no leakage. The probe is constructed with a 316L stainless steel housing and sheath for strength and corrosion resistance. For ease of mounting, the PR-25AP is available with the following mounting thread options:
1/2NPT 3/8NPT 1/4NPT Non-Threaded Housing
The mounting thread options above allow the probes to be used in a wide variety of applications, including:
As stand-alone immersion sensors. Installed directly into your product or process using an NPT threaded port. The non-threaded design can be combined with our M12-Handle accessory to convert it for hand-held sensing applications. Other applications using a variety of available compression fittings or other accessories.
The PR-25AP, like all of our M12 enabled probes, comes standard with a 4-wire, 4-pin, M12 A-Coded plug connector for easy assembly to extension cables. This allows it to be used in any 2, 3 or 4-wire measurement system for maximum flexibility. For 1/10DIN accuracy we highly recommend using a 4-wire measurement to take maximum advantage of the tight accuracy option.

Is your "1/10 DIN" RTD actually "1/10*Class B" across their full operating range or only at 0°C? For example, is their accuracy ±0.13°C at 200°C (1/10 of Class B, which is ±1.30°C) or something else? If something else, please provide a formula or table.
Thank you for your inquiry. This is the tolerance equation for it: 1⁄10 DIN = ±1⁄10* (0.3 + 0.005*t)°C or 100.00 ±0.03 Ω at 0ºC

What is the 50% response time for these sensors?
Thank you for your inquiry! 50% Response is the time the resistance thermometer element needs in order to reach 50% of its steady state value. 90% Response is defined in a similar manner. These response times of elements are given for water flowing with 0. 2 m/s velocity and air flowing at 1 m/s. For more information on RTD response time, please see this Technical Reference from our UK site: https://www.omega.co.uk/temperature/z/resistanceelements.html

can you tell me the response time? the documentation just says fast. How fast?

Is this temperature probe submersible into liquids?
Thank you for your inquiry. This air probe is designed for measuring air only and cannot be submersed in liquids. We offer sealed probes that are designed for liquid submersion.
Date published: 2020-11-19
I know what a response time is and that they are determined either in water at 0. 2 m/s velocity and air flowing at 1 m/s. What is the response time for this sensor?
Thank you for your inquiry. Response Time would be less than 5 seconds.
