Datasheet

The mechanical differential pressure switch ⁄ differential pressure monitor PREMASREG
®
DS 1 with metal angle is used for monitoring above-
atmospheric, differential, and below- atmospheric pressures of air and gaseous, non-aggressive media in air ducts, ventilation intake or exhaust
devices, as a flow monitor, as a pressure difference detector or pressure monitor for flow detection at electric heating registers, for monitoring
V-belts and filters, as air pressure deficiency protection, for monitoring fans and air dampers, or as a limit value controller. The switchpoint is
adjusted using the internal precision scale. These instruments are factory - calibrated. The differential pressure DS 1 switch is supplied including
connection set
ASD-06 (2 m connection hose, two pressure connection nipples, screws) and mounting angle DS1 - MW- Z .
TECHNICAL DATA
Switching capacity: 5 (0.8) A, 250 V AC
(Contact load) 4 (0.7) A, 30 V DC
Contact: single-pole potential-free changeover contact,
multi-layer contact, gold-plated (DDC compatible)
Pressure range: see table, high adjustment accuracy due to individual laser-etched scale for each switch
Enclosure: base: material PC (10 % GF), colour light grey (similar to RAL 7035),
snap-on lid: material PC, transparent, cable gland PG 11 with strain relief
Temperature of medium: –30...+85 °C
Membrane: silicone, LSR (Liquid Silicon Rubber, tempered at +200 °C, non-outgassing, LABS-free,
no emission of varnish-adhesion inhibiting substances),
long-term stability of switching points due to trapezoidal bead membranes
Humidity: < 90 % r. H., non-precipitating air
Electrical connection: 0.14 - 1.5 mm
2
, via terminal screws on circuit board
Pressure connection: P1(+) for higher pressure
P2(–) for lower pressure
Ø 6.2 mm (nipples)
Mounting:
with metal angle DS 1 - MW- Z (included in the scope of delivery) (for other optional shapes, see table)
Recommended mounting position:
vertical (pressure connections downward) – factory setting; horizontal (cap up ⁄ down)
Protection class: II (according to EN 60 730)
Protection type: IP 54 with top cover (according to EN 60529)
Standards: CE conformity, low-voltage directive 2014 ⁄ 35 ⁄ EU
Tests: DVGW (according to DIN 1854), VDE 0630, EN 61058,
directive on gas devices 2009 ⁄ 142 ⁄ EU, CE 0085 A P 0918
FUNCTION Contact 1 - 2 breaks when pressure ⁄ differential pressure rises to the preset value.
Contact 1 - 3 closes when pressure ⁄ differential pressure drops and can be used as signal contact.
