Description
- JUNG PUMPEN
- Hydrostatic level transmitter HD04 Ex
- Hydrostatic level transmitter for
- water level dependent control of
- maximum three explosion-proof
- submersible motor pumps, as well as alarm at
- unacceptably high water level
- in the collection shaft.
- The filling level of the shaft is
- continuously detected by an immersion probe
- .
- The input current signal (4-20 mA) of the probe is evaluated and
- shown on the display as cmWS. At the same time,
- it is checked whether the value has reached
- the switch-on point of one of the four relays
- and the relays are then switched
- accordingly.
- The level control in detail:
- > Casing with door, IP 44,
- 250 x 250 x 155 mm (HxWxD),
- > Microprocessor electronics with 4 relay
- outputs, programming buttons and
- 2-line graphic display
- > Max. Switch-on point: 4 mWS
- > smallest level difference: 1 cmWS
- > safety barrier
- Ex II (2) G (Ex ia) IIC/IIB
- > immersion probe made of stainless steel 1.4571 with
- 10 m PUR cable and
- integrated air hose for
- atmospheric pressure equalization.
- ATTENTION: It is therefore not possible to
- extend this on site.
- > Ceramic separating membrane,
- pressure-resistant up to 10 mWS and short-circuit-proof
- > Output signal 4-20 mA, temperature-
- compensated, 2-wire technology,
- accuracy: +/- 0.5% of
- full scale value
- > Cable gland with locknut
- for mounting on a crossbeam.
