Food Grade 90° Angle sharp Bent Probe DS18B20 digital Temp Sensor
Food Grade 90° Angle Sharp Probe DS18B20 Digital Temp Sensor, It’s using the original Dallas DS18B20 chip. Its unique single-line interface makes it easy to communicate with equipment. It can convert the temperature to 12 digital words in 750 milliseconds (maximum). In addition, it can measure temperatures from -55°C to +125°C(-67F to +257F).This products is customization one based on customer request. The dimension of probe is 7*300mm, because the ds18b20 chip diameter is at least 5mm, so the probe dimension is greater than or equal to 6mm easy to assembly. Considering that the probe needs to be bent, so the glue injection requirements are strict.
Votesen VTS200 is a DS18B20 digital temperature sensor which composed of original DALLAS chip, probe, cable and connector and custom labeling and packaging options are also available.

In addition to industrial and agricultural, medical, meteorological, environmental protection, food processing and other equipment in the temperature measurement and control circuit, automation office appliances.
Q: Where physically on the device does the temperature measurement take place?
A: The DS18B20 does not sense temperature directly through the package. For all package types, the DS18B20 senses temperature primarily through the GND pin. Ensuring a good thermal connection between the GND pin of the device and the heat source you wish to measure will provide the best results.
Q: Is there a way to extend the temperature range of the DS18B20?
A: No, there is not a way to increase the range it reads. The DS18B20 reads with an accuracy of ±0.5°C from -10°C to +85°C and ±2°C accuracy from -55°C to +125°C.
Q: Will a conformal coating affect the thermal response of the DS18B20?
A: A thin conformal coating will not affect the thermal response of the device.
Q: Using OneWireViewer, can more than one DS18B20 be logged?
A: Yes, every DS18B20 will have a file where you can store the data. Data will be received from one DS18B20 at a time.
Q: Can you power the DS18B20 from a 3V battery?
A: The DS18B20 can be powered from any source. Since batteries will dip in voltage, a nominal 3V battery may not always supply the minimum 3.0V the DS18B20 requires. We suggest a step-up voltage regulator is used to ensure the device is supplied within its rated voltage range of 3.0V to 5.5V.
