KP15Pressure Transmitter

Fluids and gases measurement(Featuring stainless diaphragm)

Overview
KP15 features diaphragm seal type pressure
sensing element with SUS316L material. The
diaphragm can accommodate various types ofﬂuids and gases measurements in applications
where low and absolute pressure measurements
are required.

Features
・SUS316L pressure receiving part material
・Lowest range 10kPa (standard type)(Compound range -5 to 5kPa)

・High accuracy ±0.25%F.S.
(Varies depending on the range)

・Available for absolute pressure range
50kPa abs., 100kPa abs., 200kPa abs.

・Response time 1ms or less・Dust and waterproof structureStandard type

Flush diaphragm type

(IP65)

・Withstand voltage 500V AC・Equipped with zero adjustment trimmer
・M12 connector connection
