max. ±0.4 %/10 K of full scale value
IP 54 per EN 60 529 / IEC 529
(with liquid filling IP 65)
1) Maximum continuous media temperature of 100 °C is recommended. However, higher temperatures can be maintained safely for short term exposure per table see below. The user should consider temperature error and gauge component degradation when exposing gauge to any medium or ambient temperature above 100 °C. For continuous use in either ambient or medium temperatures above 100 °C, a diaphragm seal or other heat dissipating means is recommended. Consult WIKA for technical inquiries and application assistance.
