Temperature Sensors

What are Temperature Sensors?

Temperature sensors convert thermal energy into an electrical signal you can monitor, log, or use to drive control actions. They’re one of the most ubiquitous measurement devices in industry — found in everything from chemical reactors and food processing lines to HVAC systems, motor windings, and pipeline monitoring. Getting accurate temperature data is essential for product quality, equipment protection, regulatory compliance, and process efficiency.

The two most common technologies are RTDs (Resistance Temperature Detectors) and thermocouples, each with their own strengths. RTDs offer high accuracy and stability over moderate temperature ranges, while thermocouples handle extreme highs and lows at lower cost. Choosing the right sensor — plus the transmitter, signal conditioner, or display that goes with it — is critical to getting reliable data at your control system. At Process Solutions Corp., we help you match the right temperature solution to your application, from simple gauge replacements to full HART-enabled smart transmitters.

Why Accurate Temperature Measurement Matters

• Process Control — Maintain consistent temperatures for product quality and repeatability
• Equipment Protection — Detect overheating in motors, bearings, and electrical systems before failure
• Safety — Trigger alarms and shutdowns when temperatures exceed safe limits
• Energy Efficiency — Optimize heating, cooling, and HVAC performance
• Regulatory Compliance — Meet documentation requirements for food safety, pharmaceuticals, and hazardous processes

Common Temperature Measurement Technologies

• RTDs (Pt100, Pt1000) — High-accuracy resistance-based sensors for stable measurement up to ~600°C
• Thermocouples (J, K, T, E, N, etc.) — Wide-range sensors capable of measuring extreme temperatures, from cryogenic to over 1700°C
• Temperature Transmitters — Convert RTD or thermocouple signals to 4-20 mA or HART for control system integration
• Signal Conditioners — Isolate, amplify, and convert temperature signals for industrial environments
• Display Indicators — Local readouts with optional alarms and relay outputs
