HM23Y Special Pressure Transducer for Oilfield and Mining Well

Description

HM23Y Special Pressure Transducer for Oilfield and Mining Well is specially designed and manufactured for very bad environment such as clogging pressure-guided hole due to slurry as well as strong vibration in oilfield drilling and well measuring. This transducer takes European advanced splashing thin / thick membrane ceramic pressure sensor as sensitive element and is integrated with electronic circuit. This type of pressure transducer is of fully stainless steel cylindrical structure, with easy operation. It is specially used for such viscous, easily clogging, strongly vibrating industrial site as well measuring in oilfield, pharmaceutical, textile etc.

Features of Product
