Straight Solid State Temperature Probe

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
