Overview
The HR-30 Series are measuring instruments that operate with the use of lead switches and
magnets; can be applied to various storage containers, including those in chemical
factories, which are highly oxidative and corrosive; can be widely used in all industrial areas;
and have high reliability and long life spans.

In the case of the HR-30 Series, the FLOAT made to fit the specific gravity of the measure
object moves up and down along with the liquid surface by buoyancy; the magnet
installed in the FLOAT operates the REED S/W to generate contact points
. Multiple
detection positions can be set to issue the level of the upper/lower limit alarms or
adjust the alarm levels.
■ Frequently used to measure most liquids (HH, H, L, LL)
■ Materials of the detecting element are resistant to corrosive measure objects (PVC, PTFE)
■ Have explosion-proof structures (Ex Version)
■ Durable and highly reliable structure
■ Shows high reliability in level detection
