DP Transmitters are CSA-Listed for Div 2 hazardous locations.
Press Release Summary:
Models 140-142 provide loop-powered, 8-28 Vdc, 2-wire, 4-20 mA transmitter for various applications. Transmitter and its terminal strip are housed in aluminum housing with ½" NPT wire access. Accuracy is ±2% from 20-100% FS, while indicator accuracy is also ±2% FS and independent of transmitter output. Design provides total separation of high and low pressures via convoluted elastomer diaphragm. Safe working pressure for aluminum and 316 SS is 3,000 psig and 1,500 psig for brass.
Original Press Release:
Mid-West Instrument Introduces 4-20mA Indicating Differential Pressure Transmitter for Models 140-142
Now CSA Listed for Div 2 Hazardous Location Service
The new Models 140-142 provide a simple, low cost Loop Powered 8-28 Vdc two wire 4-20mA Transmitter for a variety of applications. The transmitter and its terminal strip is housed in an aluminum housing with ½" NPT wire access for easy access for field wiring. Accuracy is ±2% from 20% to 100% of full scale. Indicator accuracy is also ±2% full scale and is independent of the transmitter output.
This design provides total separation of high and low pressures by a convoluted elastomer diaphragm. The units are available with pressure containing elements of aluminum, brass or 316 S.S. Safe working pressure for aluminum and 316 S.S. is 3000 PSIG and for brass it's 1500 PSIG. Full over-range protection is provided to full Safe Working Pressure. Differential Pressure ranges from 0-20 in. H20 to 0-100 PSID (0-50 mbar to 0-7 bar) Gauge fronts are of reinforced, engineered plastics to eliminate corrosion.
Benefits:
Indicating Transmitter is an option on all new, 140-142 Models
Easy Field Wiring
Total separation of high and low pressure
Full Over-Range Protection
Corrosion Resistant Gauge Fronts
