ET341 · Measuring Ambient Properties: Thermal and Environmental Card

Measuring Ambient Properties: Thermal and Environmental Card

A comprehensive course package for the ET platform: hands-on exploration of ambient and atmospheric measurement using industrial-standard sensors. This unified module features both the Thermal Card and the Environmental Card, powered and monitored by the ET300 base system, complete with guided multimedia courseware for the study of non-electrical physical quantities.
Experiments
  • Thermal Studies: Measurement of temperature using a Type K Thermocouple, NTC Thermistor, Platinum RTD (PT100), and an IC Temp Sensor (LM35)
  • Environmental Studies: Measurement of atmospheric pressure, air velocity, and relative humidity
  • Analysis: Comparative analysis of sensor response times, sensitivity, and accuracy across different ambient conditions
  • Calibration: Calibration and linearization of thermal and environmental measurement chains
ET341 Thermal and Environmental experiment cards
Description
    The platform teaches the fundamentals of measuring ambient physical quantities through guided, hands-on experiments.
  • The Thermal Card carries an integrated heating element alongside four distinct temperature sensors, allowing students to safely generate controlled thermal environments.
  • The Environmental Card features specialized sensors for air pressure, airflow, and humidity, allowing students to observe real-world atmospheric variables in real time.
    • Accessible measuring points on both cards expose the raw outputs of each sensor. These are acquired and displayed by the base system's virtual instruments, allowing for a direct, side-by-side comparison of different measurement technologies.
Courseware
    The interactive multimedia course combines theory with guided experiments: principles of thermoelectricity, resistance-temperature relationships, thermal anemometry, and capacitive humidity sensing. Student answers are evaluated automatically, and the full course-at least 8 hours of directed instruction (4 hours per card)-is available with multi-language support.
Scope of delivery
  • 1x Thermal experiment card with integrated heater and sensors
  • 1x Environmental experiment card with integrated sensors
  • Storage case(s)
  • Multimedia course software with course browser
  • Connection cables
