Optris - Model CSlaser LT -High-Performance Single-piece Industrial Infrared Pyrometer with Laser-Sighting

The Optris CSlaser LT is a high-performance infrared thermometer designed for precise and reliable non-contact temperature measurement, covering a range from -30 °C to 1000 °C. The pyrometers robust, single-piece design ensures easy integration into process systems, making it a preferred choice for professionals across various industries. Key features include double laser spot marking, a superior distance-to-spot size ratio, and durable stainless steel housing (M48x1.5). With measuring spots starting as small as 1.4 mm and response times from 150 ms, this IR pyrometer excels in demanding industrial environments.

The CSlaser LT infrared pyrometers redefine precision and reliability in non-contact temperature measurement, providing essential temperature monitoring solutions for fixed-installed or fixed-mounted applications. Their non-contact nature makes this infrared thermometer ideal for processes where direct contact is impractical, such as with inaccessible or moving products.

Compared to smaller sensors from the CSlaser LT and CSmicro product lines, the CSlaser stands out with its innovative double-laser sighting system. This system accurately marks measurement targets, ensuring precise temperature readings. Additionally, this IR pyrometer can operate in ambient temperatures up to 85 °C without additional cooling, further enhancing its versatility.

The CSlaser LT is a versatile instrumentation tool, functioning both as an analog device with a 4-20 mA signal and an alarm output (open-collector) and in digital mode via an optional USB programming kit. The standard two-wire interface simplifies cabling and ensures reliable data transfer to a PLC. In digital mode, the sensor and laser are powered by the USB interface’s 5 V. The sensor offers two modes of digital bidirectional communication, allowing for data exchange in both directions, as well as a unidirectional burst mode for continuous data transmission. Additionally, the CSlaser can operate simultaneously in digital and analog modes, powered by the USB interface.

A standout feature of the CSlaser LT series is its double laser aiming marks, which indicate the exact spot location and provide valuable information about the spot size. This ensures operators have a clear understanding of the measurement area, enhancing accuracy and reducing errors. The double laser beams follow the infrared optical path to mark the measurement spot at any distance, crucial for precise temperature measurement in industrial areas and research and development. Various focus versions allow flexible adjustments for different applications.

The CSlaser LT series offers exceptional optical resolution, up to 50:1, ensuring precise temperature data even in narrow field-of-view conditions. Available in multiple versions with different close-focus optics, the CSlaser LT provides unparalleled accuracy and versatility in non-contact temperature measurement technology.
