Pressure transmitters in Bangladesh

Pressure type

Gauge (relative to atmosphere), absolute, sealed or differential (for filters, flow and level).

Range and accuracy

Choose a range so normal pressure sits in the upper half; accuracy from about 0.05% to 1% FS.

Process connection and materials

¼ or ½ in NPT/BSP, flush diaphragm for viscous or dirty media, 316L or Hastelloy wetted parts for corrosive service.

Output

4–20 mA two-wire is standard; HART, Modbus RS485 and voltage outputs are common options.

Hazardous areas

Intrinsically safe (Ex ia) with a barrier, or explosion-proof/flameproof (Ex d) housings for Zone 1/Class I Div 1.

Both convert pressure to an electrical signal; 'transmitter' usually means an amplified 4–20 mA or digital output, 'transducer' often a mV or voltage output. The names are often used interchangeably.

It depends on range, accuracy, output, connection, materials and approvals. Send the details and we quote within 24 hours. Brands we list: Yokogawa, WIKA, Rosemount, Keller, Core Sensors, NOSHOK, APG and Rosemount(Emerson).
