Thermometrics is now manufacturing Direct-to-Digital Temperature Sensors.
These units provide a 9-bit Digital Output over the Temperature Range -55° to +125°C (-67° to +257°F) in increments of 0.5°C (0.9°F). These sensors can be configured in most packages suitable for RTD's with diameters of .250" and larger.
1 Wire, 2 Wire, 3 Wire and SPI buses are available.
Each unit contains a unique serial number integral to the silicon chip so that multiple units can be wired onto a single 1-wire bus, and each is recognized by its own serial number. This feature suggests applications in HVAC and other areas where multiple temperatures need to be economically monitored by a central station.
Interface materials (both hardware and software) are available to provide readout and alarm functions right through the serial port on your PC.
Specifications are as follows:
- Direct-to-Digital Output.
- Accuracy +/-0.5°C from -10° to +85°C with 9-bit resolution.
- Temperature Range: -55° to +125°C.
- Power Supply Range: 3.0 to 5.5 VDC.
