DPD1T / DPD2T Diaphragm Differential Pressure Switches
The Barksdale DPD1T and DPD2T are housed diaphragm differential pressure switches for monitoring pressure or vacuum differentials in industrial systems. The DPD1T provides one setpoint; the DPD2T provides two independent setpoints. Both use a covered terminal strip, tamper-resistant external adjustment, a die-cast aluminum enclosure, and separate high- and low-pressure ports.
- Pressure ranges: 3SS, 18SS, 80SS and 150SS (model-dependent); vacuum ranges: 3SS and 18SS
- Single- or dual-circuit SPDT snap-action switching
- Accuracy: ±0.5% of the adjustable range
- Operating temperature: -65 to +165°F (-54 to +74°C)
- NEMA 4 die-cast aluminum enclosure; optional NEMA 4X
- 1/8 in. NPT female high- and low-pressure connections
- Optional limit switches, CSA-approved configuration, factory preset and, on DPD2T, a 6-contact terminal block
