Smart Laser Level Transmitter Features Explosion-Proof Ratings and HART Protocol



Houston, TX (October 3, 2007) - K-TEK, announced at ISA Expo 2007 the SureShot 140XP Explosion-Proof, Smart Laser Level Transmitter. The device is designed for precise level, distance, and position measurement of dry bulk solids, opaque liquids, and slurries in challenging environments. High performance optics include a measurement laser and an aiming laser to assist with alignment. The device is capable of measuring over extended distances, up to 240 ft (75 m) with narrow beam. No beam divergence means no false echoes so accurate targeting is easy, even in silos or vessels that have complex internal structures or mixing equipment. An integrated graphic display provides easy readout viewing and the user-friendly setup menu supports a wide range of languages for quick setup in virtually any region of the world. Housed in an explosion-proof assembly with screw-on, glass cover for quick and easy access, the SS 140XP meets the requirements for use in hazardous areas and is rated for IP67 or NEMA 4X, Class I Div. I Group A, B, C, & D ratings.


The SureShot140XP accurately measures distances up to 240 feet (75 meters). A precise, pulsed laser diode features no beam divergence and, therefore, no false echoes. The laser can be directed through very tight spaces, as small as three inches in diameter. This means accurate readings in silos with internal structures or build-up.


"The SureShot laser transmitter combines a unique set of features that are ideal for a variety of challenging environments and applications," stated Ivo Radanov, Product Manager for Laser Products at K-TEK. "The narrow parallel laser beam and the ability to detect surfaces at oblique angles means consistent performance in tight spaces with complex structures and easy installation on existing silo nozzles, regardless of where the nozzle is located. The system is completely immune to reflections and echoes, providing accurate readings on solids with immunity to 'cone up' and 'cone down' variations in the material being measured. Add in the ability to accurately measure to the very bottom of the silo cone, to the last gram of material remaining, and we have a product that goes far beyond where other non-contact technologies stop."


The SureShot140XP is a compact and modular unit featuring a unique, all-digital design. No calibration or special configuration software is required, so setup and troubleshooting are quick and simple. An integrated graphic display with push buttons allows easy setup and detailed viewing of menus and readouts. A choice of languages is offered, including English, Spanish, French, Portuguese, Italian, Russian, and Mandarin.


Geared to last pulse detection, the SureShot140XP is able to select true signals even in the presence of surrounding noise, such as chemical vapors, dust, or agitator blades. The transmitter's variable gain provides reliability measurements in environments with quickly changing visibility conditions, even in the presence of dust, vapors, and smoke.

Color compensation corrects for weak or excessive return signals, even at high speeds. Readings can be updated as quickly as three times per second. A sophisticated digital filtering system rejects atypical readings and selects true signals.


The standard housing is powder-coated aluminum with optional stainless steel for corrosive environments. Stainless steel dust tubes prevent dust build-up and protect the optical lens from being coated. The dual-compartment design isolates wiring and terminations from sensors and internal electronics. The system features such output options as 4-20 mA and HART.
