Varied data output formats expand digital temperature sensor options

May 10, 2013 // By Graham Prophet
Measurement Specialties has released a family of compact digital temperature sensors that easily integrates into a variety of industrial control, HVAC/R and heating/cooling systems. TSYS02 combines low power, high accuracy in an ultra-small TDFN8 package.

The series’ performance-cost ratio makes these sensors suitable for automotive and medical applications, and the SMT-compatible package enables the sensors to be used in high volume applications for on-circuit temperature control. Designed with ease-of-use and flexibility in mind, these fully-calibrated sensors come in three different data output options:

  1. TSYS02D has I 2C (Inter-Integrated Circuit) for integration into digital interface bus systems.
  2. TSYS02P has PWM (Pulse Width Modulation) for integration into simple control units.
  3. TSYS02S has SDM (Sigma Delta Modulation) for integration into analogue circuitries.

16-bit temperature sensing resolution combined with the low power and highly accurate characteristics make these sensors cost-effective replacements for thermistors, NTCs (negative temperature coefficients) and RTDs (resistance temperature detectors). Available in a compact TDFN8 surface mount package, the TSYS02 measures 2.5 x 2.5 mm, while drawing a maximum of 12.5 µA. Operating temperature range is -40°C to +125°C. Every TSYS02 is factory-calibrated to provide a high accuracy of ±0.2°C. Custom calibration is also available to meet specific application needs. Pricing for a TSYS02 is $1.85 (10,000).
