TK-PRS021 Honeywell PLC Programmable Logic Controller 50W/250W 3.3VDC 24V DC
The TK-PRS021 is a high-performance, industrial-grade Pressure Sensor/Transmitter manufactured by Honeywell Sensing and Control. Designed for demanding process and industrial applications, it provides a reliable and accurate measurement of pressure, converting the physical input into a stable analog electrical signal. This sensor is engineered to deliver precise, long-term stability and durability in harsh environments, making it suitable for integration into control systems, monitoring equipment, and safety-critical applications.
-
High Accuracy and Stability: Features advanced sensing technology (typically based on a micromachined silicon piezoresistive sensor) to provide highly accurate and repeatable pressure measurements with excellent long-term stability and minimal drift.
-
Rugged Industrial Construction: Housed in a robust, stainless-steel package with options for various process connections, offering high resistance to vibration, shock, and corrosive media. Many variants are rated for high overpressure and burst pressure.
-
Wide Operating Range: Available in multiple pressure ranges (spanning from low vacuum to high gauge or absolute pressures) to suit diverse application requirements. The TK-PRS021 model suffix specifies the exact range and output.
-
Temperature Compensated: Features integrated temperature compensation circuitry to ensure accurate readings across a wide operating temperature range, minimizing errors caused by ambient temperature variations.
-
Multiple Electrical Outputs: Typically provides industry-standard analog outputs such as 4-20 mA two-wire or 0.5-4.5 V ratiometric, ensuring easy compatibility with PLCs, data loggers, and other control equipment.
-
Media Compatibility: The wetted materials, often 316L stainless steel, are selected for compatibility with a wide range of gases and non-corrosive liquids.
TK-PRS021 Material & Applications
-
Material: The sensor body and diaphragm are typically constructed from 316L stainless steel for excellent corrosion resistance and media compatibility. The internal sensing element is a micromachined silicon chip. Electrical connections are made via a sealed cable or connector, and the housing is often potted for environmental protection.
-
Applications: Widely used in industrial automation, hydraulic and pneumatic systems, compressor monitoring, process control (chemical, pharmaceutical, food & beverage), test and measurement equipment, HVAC/R systems, and mobile/off-highway vehicle systems for monitoring fluid and gas pressures.
