Stainless steel HART immersion probe
Item number: LMK 458H Applications Shipping
Price on request
Delivery time:Delivery time on request
The LMK 458H level probe is designed to detect levels in service and product storage tanks and is certified for shipbuilding and offshore applications. A temperature application range of up to 85°C and use in hazardous areas make it possible to measure the pressure of a wide variety of liquids under extreme operating conditions. The basis of the LMK 458H is an in-house developed capacitive ceramic sensor element with high overload capacity and media resistance.
