Digital Temperature Sensors

Measurement Specialties has recently released the TSYS02 family of compact digital temperature sensors that easily integrates into a variety of industrial control, HVAC/R and heating/cooling systems. The series' good performance-cost ratio makes these sensors apt 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:TSYS02D: I2C (Inter-Integrated Circuit) for integration into digital interface bus systems; TSYS02P: PWM (Pulse Width Modulation) for integration into simple control units; TSYS02S: SDM (Sigma Delta Modulation) for integration into analog circuitries. The 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 an ultra-compact TDFN8 surface mount package, the sensor measures only 2.5 mm x 2.5 mm, while drawing a maximum of 12.5 μA. Operating temperature range is -40°C to +125°C. Every sensor is factory-calibrated to provide a high accuracy of ±0.2°C. Custom calibration is also available to meet specific application needs.
