The Allnet temperature sensor ALL3008 is a cable-connected sensor for measuring ambient temperature in indoor environments. It is specifically designed for use in IP-based building automation systems and is used to capture temperature values in the range of -55 °C to +80 °C. The measurement is performed via a 13-bit ADC, enabling a temperature resolution of 0.03125 °C. The temperature accuracy is ± 1 °C in the range of -25 °C to +100 °C. The sensor features a 1 m long connection cable, allowing flexible installation at various locations indoors.

Applications

The sensor is intended for indoor use and is suitable for applications in buildings where continuous temperature monitoring is required. This includes, for example, office buildings, apartments, industrial facilities, or server rooms, where temperature is relevant for operational safety or comfort. The sensor is used in conjunction with compatible MSR central units that collect and process the captured data.

Functions and Equipment in Detail

The ALL3008 captures ambient temperature with high resolution and transmits the values via the 1 m long cable to a central control unit. The accuracy of ± 1 °C in the range of -25 °C to +100 °C ensures reliable measurement under most indoor conditions. The 13-bit resolution enables fine representation of temperature trends, which is important for precise control and analysis. The sensor is designed exclusively for indoor use, with environmental conditions such as humidity and mechanical stress remaining within the specifications of the central unit.

Technology Explained Simply

The sensor uses a 13-bit ADC (analog-to-digital converter) to convert the analog temperature measurement into digital values. These values are transmitted via the connection cable to the MSR central unit. The resolution of 0.03125 °C means the sensor can detect even the smallest temperature changes, which is advantageous for applications requiring high measurement accuracy. The accuracy of ± 1 °C in the range of -25 °C to +100 °C is sufficient for most indoor environments and ensures reliable data acquisition.

Compatibility and Accessories

The temperature sensor ALL3008 is compatible with various MSR central units from the manufacturer Allnet, including models ALL3419, ALL3500, ALL3500PoE, ALL3696, ALL3420, ALL5000, ALL4500, ALL5000v2, ALL3418, ALL5100, ALL4176, and ALL3692. The connection is made via a sensor port, with only one sensor from the list ALL4454, ALL4432, ALL4421, ALL4590, ALL4532, ALL4552, ALL4522, ALL3005-6, ALL3015, ALL4006, ALL4506-7 allowed per port. Suitable central units that can be used with this sensor include, for example, the MSR central unit ALL3500v2 with 4 sensor ports and WLAN, the central unit ALL3419 with 3 sensor ports and WLAN, and the central unit ALL5000v2 with 16 sensor ports and 48,3 cm ( 19 inch ) mounting.

Installation and Mounting

Installation is performed via the 1 m long connection cable, which is connected to the appropriate interface of the MSR central unit. The sensor itself is positioned at the desired measurement location indoors. Mounting requires no special tools or additional components. The positioning should ensure that the sensor is not influenced by direct heat sources, airflows, or other disturbances to guarantee representative temperature measurement.

Advantages in Operation

The ALL3008 provides reliable and precise temperature measurement for indoor environments. The high resolution and accuracy within the relevant temperature range enable accurate monitoring and control of climate systems. Compatibility with various MSR central units offers flexibility in system selection. The simple installation and cable-connected connection ensure stable and maintenance-friendly integration into existing building automation systems.
