RH-Analog Linear Position Sensor  

Feature

       RH series linear position sensors which are of circule tube and pressure-resistantance,are applicable to the built-in installation of hydraulic oil cylinder. The features:anti-interference ability, good environmental tolerance, neverwear,high precision,superior resolution,replacement by convenience,online intelligent diagnosis and other special advantages;      

        Analog outputs includee: dc current 4 ~ 20 mA (forward, reverse) and dc voltage 0 ~ 10 V (forward, reverse); SSI outputs includee: 24, 25, 26 bit binary or gray code; Measuring start-stop points can be adjusted in full range,the products can be widely used in metallurgy (continuous casting and rolling), petrochemical, port machinery, hydraulic pressure tester,water conservancy and electricity, etc.

 

External installation,easy to use.

Absolute location output,no need to return to zero.

Non-contact measurement,no physical deterioration forever.

High resolution,analog output 16 binary digit D/A,infinite resolution.

Nonlinearity degree,<±0.01%F.S.

Repeatability precision,< ±0.001% F.S.

LED for sensor diagnostics

Modular design,convenience to replace.

Low power dissipation, good for reducing the system temperature drift.
