SF52 Dew-Point Transmitter for Industrial Dryers
Simple, cost-effective OEM dew-point transmitter for harsh dryer environments.
Key Features
- Measurement range −40°C to +60°C dew point
- Accuracy ±2°C dp
- Voltage (0-1V, 0-5V, 0-10V) or 4-20 mA 3-wire outputs
- Traceable 3-point calibration certificate
- Recessed, protected measuring element for extended life
- Rugged IP66 / NEMA 4 nickel-coated brass housing
- G1/2" BSP or 1/2" NPT process connections
- High-volume OEM calibration system for short lead times
Overview
The SF52 is a simple, cost-effective dew-point transmitter designed for OEM industrial dryer applications where reliability and toughness are needed at an economical price point. A recessed, protected polymer sensing element gives it an extended service life in harsh drying environments.
Working Principle
A polymer-based capacitive sensor changes in proportion to adsorbed water vapour. The recessed sensor housing protects the element from mechanical and thermal stress, while onboard electronics output a voltage (0-1V, 0-5V, 0-10V) or 4-20 mA signal scaled to dew point or absolute humidity.
Applications
Benefits
- Economical option for OEM dryer manufacturers
- Tough, recessed sensor withstands harsh drying conditions
- Flexible output options simplify integration with existing controllers
- Short delivery lead times for OEM production volumes
