Sentry Equipment Corp Receives Patents for New ISOLOK® Sampler

Oconomowoc, Wisconsin - Sentry Equipment Corp announced that the U.S. Patent & Trademark Office has granted the company patents for its severe-duty automatic sampler. United States patent number 7,481,124 entitled "Positive-Displacement Sampling Apparatus" covers the design of the ISOLOK® SAL-DBB sampler. The SAL-DBB is a double block and bleed automatic sampling device that uses ISOVALVE® technology, a feature unique to Sentry's family of ISOLOK® samplers.

The ISOLOK® SAL-DBB is the next generation of automatic sampler for harsh operating conditions - such as oil sand mining - and offers the best operator protection in the industry. The ISOLOK® SAL-DBB sampler is designed to be fully isolated from the process before the removal of any fasteners to take the unit off the line. Additional features include the patented "park position" feature and a new, lighter-weight removable assembly.

According to Bill Werra, Business Unit Manager at Sentry Equipment, "The ISOLOK® SAL-DBB unit is by far the safest isolatable automatic sampler on the market. We worked with our clients to get their input on the design criteria and it was during this process that they identified that safety was their number one concern. Not only is the unit safe and reliable, but the operating costs of the SAL-DBB are a fraction of others on the market."

Extensive testing of the new sampler has shown that clients can expect to see an increase in up time and a decrease in maintenance costs. The companies who conducted the on-site testing concluded that switching to the ISOLOK® SAL-DBB will save them substantial time and money.
