A new gauge uses a laser beam to measure the level, distance and position of dry bulk solids, opaque liquids, and slurries in complex containers.
K-Tek said its SureShot 140XP has optics that include a measurement laser and an aiming laser to assist with alignment.
The system is immune to reflections and echoes, providing accurate readings on solids with immunity to 'cone up' and 'cone down' variations in the material being measured, the company claimed.
"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," K-Tek stated.
The device is capable of measuring over extended distances, up to 240 ft (75m) with narrow beam.
A pulsed laser diode features no beam divergence and, therefore, no false echoes, the company claimed.
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, stated K-Tek.
"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," the company claimed.
An integrated graphic display provides easy readout viewing and the setup menu supports a wide range of languages for quick installation, the company claimed.
The device is housed in an explosion-proof assembly with a screw-on, glass cover for quick and easy access.
"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 company stated.
The SureShot140XP is designed as a modular unit featuring a unique, all-digital design.
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 company claimed.
The transmitter's variable gain provides reliability measurements in environments with quickly changing visibility conditions, even in the presence of dust, vapors, and smoke, stated K-Tek.
A colour compensation design corrects for weak or excessive return signals, even at high speeds. Readings can be updated as quickly as three times per second.
A 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.
