9-Bit Digital Temperature Sensor Assembly
Si18DTsens digital temperature
assembly is used as a plug-in accessory with all Signal Consulting,
LLC Controller Boards when medium resolution (+/- 0. 50
C) temperature measurements are required. This assembly uses a
small, 9-bit Digital Thermometer (sensor) manufactured by Dallas
Semiconductors with part-number of: DS18S20,
www.dalsemi.com. It can measure temperature from -550
C to +125 0 C with +/-0. 50 C resolution and
with +/- ½ 0 C accuracy. Because this sensor is digital
in nature, it is virtually immune to noise or loading and it is
ideally suited for remote sensing applications. This sensor is
factory calibrated by Dallas Semi and has excellent log-time
stability. In addition, this sensor has a small thermal-mass and a
Si18DTsens assembly includes the
DS18S20 sensor, Teflon-coded #24 gage, 12” long, connecting wires
(to minimize thermal-conduction) and a small 3-Pin Molex
22-01-3037 Polarized FN Connector for quick connectivity.

uses a unique “1-wire interface” that can operate in parasite power
mode. In this mode, it requires only 2-conductors for reliable remote
(long as 20 meters) temperature sensing. See diagram below for parasite
power mode in remote sensing application.
