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:
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.
When ordering your PR-25AP sensor, don't forget your extension cable. Omega offers a wide selection of extension cables including over molded PVC, Polyurethane and Silicone cables, as well as customized cables in a variety of materials with optional stainless steel braid or hose for improved mechanical protection, and a wide selection of instrument connections.
Connect your PR-25AP RTD sensor to one or more of Omega's wide variety of in-stock controllers, data loggers, transmitters, hand held thermometers, PLCs, or other measurement & control products to complete your measurement or control system. Omega offers a selection of programmable and fixed range transmitters that can be connected directly to the M12 connection of your PR-25AP sensor. There are also wireless transmitter options available.
