The pressure transmitters of type 681 with piezoresistive
meas uring elements have compensated, calibrated and amplified
sensor signals which are available as stand ard voltage or
current outputs.
In the immersion-sensor version with a salt water and oilresistant
connection cable they are specially suited for level
measurement, even in the presence of corrosive liquids.
The cable incorporates a tube for compensation of the ambient
pressure.
Manufactured from stainless steel, its welded construction
provides a watertight seal.
Pressure range: 0 ... 1000.... 0.. 25000 mmH2O
output: 4..20 mA
Accuracy :0.25%, 0.5%
Maker: Huba Control , Swiss.
