The TK3051P High Temperature Anti-Corrosion Pressure Transmitter is configured from the TK3051T series for high-temperature, corrosion-resistant and remote diaphragm-seal pressure measurement. Gauge or absolute pressure sensors, fill fluids, temperature isolators, capillary tubes and flange or threaded process connections can be selected for the application.
- Pressure measurement in high-temperature process media.
- Pressure measurement in corrosive media.
- Installations requiring a remote diaphragm seal or temperature isolation.
- Petroleum, chemical and other process equipment requiring corrosion-resistant wetted materials.
- Hazardous areas requiring intrinsic safety or explosion suppression certification.
- High-temperature isolation: High-temperature oil, a 100 mm temperature isolator or a 1 m capillary can be selected.
- Selectable pressure type: Gauge and absolute pressure sensor configurations are available.
- Multiple ranges: Gauge pressure sensors cover 40 kPa to 40 MPa; absolute pressure sensors cover 40 kPa to 4 MPa.
- Wetted material options: 316L stainless steel, Hastelloy C276, tantalum and PTFE-coated 316L stainless steel are available.
- Flexible process connections: G1A, G1/2A and G2A external threads, welded threads, flat flanges and extended structures are available.
- Selectable output: 4-20 mA analog output and 4-20 mA/HART communication are available.
- Hazardous-area certification: Ex ia IIC T4/T6 intrinsic safety and Ex d IIC T4/T6 explosion suppression configurations are available.
