説明

Durable and maintenance-free
The sensor has been tried and tested in the field for years and is extremely reliable. Up to 10 million load cycles are no problem for the model R-1. The model R-1 has been designed without elastomer seal, the high-accuracy measuring cell is welded directly to the process connection. All parts that come into contact with the substances in the refrigerant circuit are made of robust stainless steel with a high load capacity.

Stable measurement in variable conditions
Due to its robust design, ambient temperatures of -25 … +85 °C [-13 … +185 °F] represent no problem for the model R-1. Even if the ensor temporarily freezes over, the accuracy is not limited.

Best possible condensation tightness
To simulate its harsh operating conditions, the model R-1 is tested in continuous operation with a cooler medium (-11 °C [12.2 °F]) for 500 h in a climatic chamber at 45 °C [113 °F] and 85 % air humidity. This quality benchmark proves the sensor’s high resistance to ondensation and ensures long-term process reliability under extreme conditions.

Safe handling of flammable refrigerants
Thanks to a technical update to the electronics, the R-1 can now also be used in applications with flammable refrigerants.

Greatest possible delivery reliability
The model R-1 is manufactured on five production lines with a high degree of automation. The highest quality is ensured by extensive quality tests that go beyond the industry standard. For example, a 100 % end-of-line test is standard at WIKA. As a strong partner in the OEM business, WIKA offers private labelling for the model R-1.
