BelGAS introduces explosion-proof two-wire transmitter
The BelGAS division of Marsh Bellofram Corp., a member of the Bellofram, has introduced a new, explosion-proof two-wire pressure transmitter, expressly designed for industrial field service.
Designed for maximum durability, the Marsh Bellofram BelGAS Type 5000 P/I transducer is a two-wire device that converts a signal pressure input into a 4-20 mA or 10-50 mA output. According to the company, the Type 5000 pressure transmitter uses a unique temperature-compensated piezoresistive transducer suitable for gauge pressure measurement of non-corrosive liquids and gases.
Available in six pressure measurement ranges from 0–15 psig (0–1.0 bar) to 0–100 psig (0–6.9 bar), the transducer features typical accuracy of ±0.1% of span, and is relatively insensitive to mounting orientation and ordinary industrial vibration. The Type 5000 can withstand overpressures to 45 psig without calibration shift and overpressures to 60 psig without failure and its operating temperature range is from –40°C to 82°C. Operating from a 12–30 VDC power supply, the transmitter has a response time of <10 milliseconds.
Other features include lightweight NEMA 4X-rated housing, a 1/4 NPT pressure port and a 1/2 NPT conduit port for field wiring. The Type 5000 is CE listed and FM-approved NEMA 4X Explosionproof to Class I, Division 1 Groups B, C, and D T6 and Dust-Ignition Proof to Classes II and III, Division 1, Groups E, F and G, T6. It also carries CSA Hazardous Locations approval to Class I, Groups B, C and D; Class II, Groups E, F, and G; and Class III.
BelGAS says the transducer is ideal for industrial field service in oil and gas, chemical processing, pharmaceutical, industrial automation, and power generation applications.
