{Root-evolved output signal}

Accuracy 1,0 % of span

Calculation the root is evolved according to the following equations:

= √ 10 x U

) U

= linear output 0 ... 10 V

= √ 20 x I

) I

= linear output 0 ... 20 mA

Electrical connection via cable gland PG 7 and internal screw terminals in the

bottom part of the case, terminal champing diameter 1.5 mm²

Ingress of protection IP54, per EN 60 529 / IEC 529

Weight kg approx. 0.6 {approx. 0.7 with power supply}

Dimensions mm see drawings

Mounting case for wall mounting

{ } Items in curved brackets are optional extras for additional price.

1) The measuring ranges 0 ... 0.1 mbar; 0 ... 0.25 mbar; 0 ... 0.4 mbar are available on request.

For these measuring ranges a larger measuring cell and consequently also a case with larger dimensions is required.

2) Only with 4 ... 20 mA 2-wire, other output signals on request.
