General Description - Sentry ISOLOK SAL-Q Installation, Operation & Maintenance Manual

General Description

The Sentry® ISOLOK® SAL-Q automatic isolatable sampler is designed to obtain samples of liquid and slurry flowing
in a process stream, into which extends a plunger with an annulus for sampling . The ISOLOK SAL-Q sampler has been
configured specifically for use in sampling the process media at the process conditions provided by the user at time of
manufacture .
Each sampler cycle consists of a plunger extension and a plunger retraction . During plunger extension, the volume of
the annulus is filled with a sample of the process stream . The plunger is then retracted into the body of the sampler,
thereby capturing a volume of sample . This sample is then deposited into a sample collection container .
The ISOLOK SAL-Q automatic fixed volume sampler is pneumatically operated . Pressurized air (or other gas) is used to
provide the force to extend and retract the plunger . When in the retracted position, air or other inert gas may be used
to assist the displacement of the sample material from the plunger annulus .
The maximum rated temperature of the ISOLOK SAL-Q sampler is defined by the plunger seals . The plunger seals are
selected based on material compatibility and temperature of the process being sampled . Reference the following
