BHS Wireless Temperature Sensor with Probe BBDS18B20

BHS Wireless Temperature Sensor with Probe BBDS18B20

A wireless sensor with an external digital probe for remote temperature monitoring where the measurement must be taken at a specific point while the device itself stays outside the monitored zone. Suitable for freezers, cold rooms, ventilation ducts, process equipment, tanks and liquids.

The probe measures temperature from -30 °C to +120 °C with ±0.5 °C accuracy and a 0.1 °C step. Every 5 minutes a reading is transmitted over an AES-128 encrypted 868 MHz radio channel to a gateway, which forwards the data to the cloud monitoring platform. There you can review measurement history and charts, set limit values, receive alerts and generate reports.

Unlike sensors with a built-in element, this model lets you pass only the thin probe through a door seal or cable entry, while the body with the batteries stays outside — this improves radio communication and makes battery replacement easier.

Key benefits

• Wide probe measuring range -30 °C…+120 °C
• ±0.5 °C accuracy across the full range, 0.1 °C step
• 1 m SUS304 stainless steel probe; longer options available on request
• The sensor body stays outside the cold or hot zone
• Replaceable 2 × AAA batteries with up to 5 years of service life
• 868 MHz wireless communication, range up to 150 m in clear line-of-sight conditions
• AES-128 data encryption between sensor and gateway
• Diagnostic button and status LED for checking the connection

Applications

• Commercial refrigeration — display cabinets, refrigerators, freezer cabinets and cold rooms
• Cold storage and food storage zones
• Pharmacies and medicine storage — refrigerators and cabinets
• HVAC and ventilation — air duct temperature monitoring
• Production equipment, pipelines and process environments
• Tanks and liquids — water, beverages, chemical and process fluids
• Server rooms and data centres
• Museums and archives

Installation

The sensor body is mounted with industrial double-sided adhesive tape on a smooth surface — plastic, metal, glass or a painted wall. No drilling or additional hardware is required. Once the body is mounted, the probe is placed where the temperature has to be measured.

Important: the probe is designed for a wide range, but the sensor body operating temperature is -20 °C…+55 °C, so the body must be positioned within these limits and inside the wireless gateway's coverage area. The device is shipped switched off; operation starts by pressing the join button and registering the sensor in the cloud portal.

Technical details

A compatible wireless gateway is required for operation. BHS specialists carry out system installation, probe placement, programming, limit and alarm configuration, and staff training.
