Description
The ControlByWeb® X-DTS-U is a compact and reliable digital temperature sensor engineered for accurate thermal monitoring in industrial, commercial, and laboratory environments. Built on the industry-standard Maxim DS18B20 1-Wire digital architecture, it delivers precise temperature data without the calibration drift or electrical noise susceptibility common to traditional analog thermistors.
Featuring a broad operating temperature range from -67°F to 257°F (-55°C to +125°C) with ±0.5°C accuracy in critical monitoring ranges (-10°C to +85°C), the X-DTS-U is an ideal choice for HVAC control, cold chain storage, environmental monitoring, and process automation. The sensor comes equipped with a 1 ft cable that can be extended up to 600 ft without signal degradation, providing exceptional setup flexibility when integrated with any 1-Wire compatible ControlByWeb controller.
Key Features
- Digital 1-Wire Sensor: Uses the Maxim DS18B20 sensor for reliable, noise-immune digital temperature transmission.
- High Measurement Accuracy: Delivers precise readings with ±0.5°C accuracy within the -10°C to +85°C (14°F to 185°F) operating band.
- Wide Operating Temperature Range: Measures temperatures reliably from -67°F to 257°F (-55°C to +125°C) across diverse environments.
- Extendable Cable Length: Supplied standard with a 1 ft lead wire, extendable up to 600 ft for long-distance remote monitoring.
- Versatile Applications: Ideal for HVAC systems, cold storage facilities, cleanrooms, server rooms, and industrial automation.
- Seamless Controller Integration: Connects directly to X-400, X-410, X-420, X-600M, XW-110, and all 1-Wire supported ControlByWeb devices.
