SELF-SANITISATION AGAINST BACTERIA AND FUNGI
Close
GW12 Digital-analogue position indicators
gravity drive, technopolymer
Main specifications
Case
Glass-fibre reinforced polyamide based (PA) technopolymer, black colour, matte finish.
Moulded-in spindle.
Bezel
Technopolymer. Moulded over the window.
Window
Transparent polyamide based (PA-T) technopolymer (practically unbreakable). Resistant to solvents, oils, greases and other chemical agents (avoid contact with alcohol during cleaning operations).
Dial
Anodised aluminium, clockwise or anti-clockwise graduation, black colour.
Reading
Five-digits roller counter and one red pointer which turns on the graduated dial. The digit of the red roll shows the decimal values, while the pointer shows the hundredth.
The display indicates the displacement of the mechanism controlled by the spindle from the start position (0). One complete turn of the machine spindle corresponds to a turn of the handwheel/knob and consequently to a turn of the red pointer. A turn of the red pointer corresponds to a determinate reading on the counter (see "reading on the counter after one revolution of the red pointer" in the table).
Ballrace rotation: maximum reading accuracy.
IP protection
The ultrasonic welding of the window to the case guarantees the complete sealing with IP 67 protection class, see EN 60529.
General information
Features and applications
The knobs with integral gravity position indicator are suitable on spindles with horizontal or max 60° inclined axis.
To choose the handwheel see the table "Handwheels/knobs - possible assembly with indicators".
Other executions
Special executions on request
- No pointer
- Plain dial
- Special dial with logo or customised graduations
- Filling with paraffin oil, maximum continuous working temperature 40°C
- Special readings after one revolution.
Instructions of use
Instructions of use
These indicators are supplied with a screw on the rear case to prevent the mechanism from rotating during transportation, avoiding any displacement of reading. Before assembling the indicator into the handwheel, it is necessary to remove the screw from the back with six-lobed socket to fit TORX®*T6 and fit the self-adhesive element supplied to guarantee IP 67 sealing.
