Supported Applications
The Omega HX300A Series consists of wall-mount transmitters designed for industrial environments requiring fast, stable, and accurate measurements. The series employs a highly stable thin-film polymer capacitor to sense relative humidity and a high-accuracy, thin-film RTD (PT100 Ω) compliant with IEC 751 and DIN 43760 standards to accurately sense temperature.
Operating Conditions & Performance
The HX300A Series operates within an ambient temperature range of 0 to 50°C (32 to 122°F). Measurement capabilities include a humidity range of 0 to 100% RH @ 0 to 50°C (32 to 122°F) and a temperature measurement range of 0 to 100°C (32 to 212°F).
Performance specifications at 25°C include an accuracy of ±2.5% RH, ±0.3°C with long-term stability better than 1% RH per year (typical). The response time is <15 seconds (90% @ 25°C in moving air at 0.5 m/sec), and temperature compensation is rated at 0.008% RH/°C (effect @ 05 RH).
The unit features a sintered filter for sensor protection and utilizes an ABS plastic watertight enclosure to NEMA 4 (IP65). Electrical connections are provided via liquid-tight nylon cable bushing fitting 5 to 10 mm dia. (0.2 to 0.4") cables.
