01DT-1L Duct/Immersion Temperature Sensor

Overview:

The 01DT-1L is a versatile temperature sensor designed for measuring temperature in duct applications, with the capability to be applied to pipe applications when used with a stainless steel or brass thermowell. Enclosed in an IP65 / NEMA 4X rated enclosure, it ensures durability and reliability in various environments, making it suitable for both indoor and outdoor installations.

Key Features:

  • Output Signal Options: Available with an NTC10k (10k2) output signal, providing accurate temperature measurement for precise monitoring and control.

  • Probe Length Variants: Offered in various probe lengths ranging from 50mm to 450mm, allowing flexibility in installation to accommodate different duct or pipe sizes and configurations.

  • High Accuracy: Provides high accuracy temperature measurement with a passive accuracy of ±0.2°C at 25°C (±0.35°F at 77°F), ensuring reliable performance in critical temperature monitoring applications.

  • Quick Response Time: Features a fast response time with typical time constants (τ) of 210 s at 0 m/s airflow and 46 s at 3 m/s airflow in air ducts, and 7-9 s with a thermowell in water pipes, ensuring rapid detection of temperature changes.

Technical Specifications:

  • Measuring Range: -50...150°C [-60...300°F]
  • Electrical Connection: Pluggable spring-loaded terminal block
  • Cable Entry: Cable gland with strain relief ø6-8 mm
