- U **Pt100 RTD with Class A Accuracy Standard (Tighter Accuracy Options Available)**
U **316L Stainless Steel** This sensor combines the **Probe and Housing** usefulness of our ultra-precise air **with Vent Holes** measurement RTD sensors with **Around Element** the convenience of our PR-21 M12 enabled RTD sensors. The design U **Temperature Range:** of the probe includes a perforated **-100 to 250°C** sheath over the sensing element **(-148 to 500ºF)** shielding it from debris while U **M12, 4-Pin, A-Coded** allowing airflow to directly reach the element. This results in **Plug Connector for** a sensor which is capable of **Easy Installation** providing accurate, fast responding U **Available With or Without** temperature measurements.
- U **Available With or Without NPT Mounting Threads**
OMEGA also offers a wide variety of compression fittings, extension cables and measurement and control instruments which allow you to fully customize the system to best meet your measurement and control needs.
- U **Probe Will Withstand 400 psi (27.6 bar) Differential Pressure Between Airstream and Ambient Conditions**
