MKS 41C Baratron® Single-End Gauge Pressure Switches (10 Torr - 500 psi)

Specifications

Full Scale Pressure Ranges:  10 Torr through 500 psi (Consult Applications Engineering on Full Scale ranges in other engineering units. Selection of trip point and Full Scale range should be as close as possible as trip point accuracy is affected by the Full Scale range)

Trip Point Range: 5% to 100% of Full Scale

Accuracy: ±0.5% of Full Scale (±temperature coefficient)

Temperature Coefficient: ±0.07% of Full Scale/°C

Ambient Operating Temperature: 0° to 50°C

Trip Point Dead Band: ±3% of Full Scale (nominal)

Response Time: <20 msec

Materials Exposed to Process Gases: Inconel and 316L S.S.

10 µRa max. on switches with Swagelok® VCR® fittings (5 µRa max. optional)

Internal Volume: 3.3 cc for single-ended, 6.6 cc for flow-through

Overpressure: 2 × Full Scale or 45 psia, whichever is greater

Outputs

Electromechanical relay: SPDT (isolated) contacts rated up to 1 Amp @ 30 VDC resistive. Relay is
