Straight Solid State Temperature Probe
Description
The BD1-xx-N is a family of stainless steel temperature probes that utilize the Brew Data BD1 solid state temperature sensing device. The solid state sensor converts temperature directly to a high level output voltage. These are straight probes with no added mounting features.
Key Benefits
- Easy to wire, no special cabling or connection requirements. Wire nuts can be used.
- Easy to interface, can be connected directly to an ADC without special signal conditioning.
- Designed for industrial environments; ESD protected and compensated to drive long cables or capacitive loads.
Key Specifications
- -40°C to +125°C temperature range
- ±0.5°C accuracy (-20°C to 100°C)
- 0.251V to 1.315V output voltage
- Single 2.7V to 5.5V input voltage
- 316 stainless steel probe body, 1/4” diameter
- High temperature 20AWG lead wires
