SENKOX HSD™ LINEAR HOT SPOT DETECTORS
Senkox HSD™ linear hot spot detectors, are advanced multifunctional detectors that provide early detection of fire or overheating conditions in the area where they have been applied, or equipment.
Senkox HSD™ Linear Hot Spot Detectors can detect in real-time the temperature, location and size of hot spots along the Senkox HSD™ Linear Heat Sensor cable. They can also provide the rate of temperature rise and the temperature difference between the hot spots and the environment. The detectors have various types of output interfaces, such as relay outputs, or analog outputs (4~20 mA or 0~5V) and a serial communication port (RS485 or RS232, Modbus/RTU protocol).
The detector consists of two main components: an HSD™ Linear Heat Sensor cable and an HSD™ DAQ module.
LHS Sensors
The Senkox HSD™ Linear Heat Sensors are designed to be highly flexible, durable, and to be applicable for different environmental conditions. The sensors withstand high temperature, high abrasion, high pressure and are oil proof.
HSD™ DAQ Modules
The Senkox HSD™ DAQ Module family is a detection control module that acts as an interface between a DCS system or fire alarm control system and Senkox HSD™ Linear Heat Sensors.

System Structure
The Senkox HSD™ Linear Heat Sensor continuously detects hot spots along the sensor cable. The hot spot signals generated from the Senkox HSD™ Linear Heat Sensor cables are acquired and processed by the DAQ Module. The processed data is output through the analog output channels (4-20 mA or 0-5V) or the serial communication port (RS485 or RS232, Modbus/RTU protocol) to the user DCS system or fire alarm system.
