Sentry Saf-T-Vise coupon holders offer ease of use and custom configuration for maximum versatility. The Saf-T-Vise patented locking collet is simple to use and enhances operator safety by safely securing the shaft within the process stream in both low and extremely high pressure conditions. These coupon holders work with a variety of corrosion coupons, including rod (cylinder), flat (strip) single hole, flat (strip) dual hole, and disk, to measure the rate of corrosion within a pressurized process such as a pipeline.
-
Sentry Saf-T-Vise probes can be inserted and retracted within a pressurized system for applications that need continual or instant corrosion monitoring. An electrical resistance (ER) probe measures both electrochemical and mechanical corrosion and is suited to corrosive environments with either poor or non-continuous electrolytes, such as vapors, gases, soils, wet hydrocarbons and nonaqueous liquids.
-
Sentry Saf-T-Vise quills offer ease of use and custom configuration for maximum versatility. The Saf-T-Vise patented locking collet is simple to use and enhances operator safety by safely securing the shaft within the process stream in both low and extremely high pressure conditions. The quills are versatile and can be configured either to inject chemicals into or take a sample from within a pressurized process such as a pipeline.
-
Sentry Saf-T-Vise insertion tools are used to place and retrieve corrosion coupon holders, injection & sample quills, or chemical injection nozzles & atomizers into high-pressure applications without interruption of the system. With their sturdy but light construction—competitor tools can weigh five times more—these tools are operated easily by only one person and are designed to make insertion and retraction under pressure safe, easy and quick.
Sample hazardous process streams safely by minimizing the escape of harmful vapors and chemicals with our portfolio of low-emission liquid and gas samplers engineered for refining and petrochemical environments.
-
The Sentry Cobra C manual gas sampler collects representative samples from gas and liquid short-chain hydrocarbon applications. This emission-free sampler uses a multi-ported valve. This valve simplifies the process of taking a sample. Additionally, it keeps the sample's integrity and handles environmental risks.
-
The Sentry Cobra DT closed loop sampler is designed to perform a detector tube measurement as safely, quickly and efficiently as possible. The Cobra DT sampler is designed with safety in mind, with a high-pressure regulator providing operators with a means to lower pressure to a safe level before inserting the detector tube. The 1000 cc cylinder allows a large volume of gas to be chambered so the operator can draw a fresh sample through the detector tube allowing a representative measurement to be collected.
-
The Sentry Cobra SS manual liquid sampler allows for safe and straightforward petroleum and natural gas sampling. The sampler design ensures a representative sample through direct connections to your lines. This Sentry low-emission sampler stands up to water corrosion and meets the highest quality and reliability standards required of petroleum sampling equipment.
-
Sentry DPA Series offers easy-to-use drip pot assemblies to collect samples within a pipeline or other pressurized system for the purpose of examining and measuring corrosion products and other contaminants, without interruption to the system. Drip pot assemblies collect the samples for analysis using a container with an interior reservoir for receiving a liquid sample, and a valve assembly coupled to the drip pot.
-
The Sentry MCG sampler is a closed-loop sampler for sampling gas. Closed-loop cylinder sampling is the safest and most effective way to obtain and transport representative samples of gases without danger to the operator or environment. A continuous flow assures representative sampling.
Steam and Water Analysis Systems (SWAS) provide real-time data needed to control and optimize water chemistry within a utility plant. A complete, fully integrated Sentry system conditions, analyzes, identifies and quantifies chemical properties to help plants produce more output while protecting their equipment and operators.
Maximize the investment of your SWAS system and ensure your sample conditioning remains up and running with continuous maintenance and replacement parts.
Find everything you need to condition a sample for pressure, temperature and/or flow rate. Select sample coolers, heat exchangers, thermal protection valves and much more based on your process environment.
-
The Sentry W7950 sparger assembly is used to prepare a sample for taking a degassed cation conductivity measurement.
-
Sentry DTC (dual tube coil) tube-in-tube heat exchangers are spirally wound, full counter flow heat exchangers well suited for a variety of applications where low flow rates of high temperature and/or high pressure fluids need cooling or heating. The sturdy tube-within-a-tube concept uses heavy duty terminal fittings to provide for a plain tube end interface for the inner tube, and a compression connection for the outer tube.
-
Sentry single line sample panels are pre-piped assemblies used to simplify the conditioning of steam, water or non-hazardous process samples. With the addition of cooling water, safe and representative samples can be obtained from individual sampling sites that are remotely located throughout the plant or from a small number of samples in a central location.
-
The Sentry TRW sample cooler cools a sample from a process stream. It may seem simple, but it is a uniquely designed small tube in a shell heat exchanger. The sample to be cooled flows through the tube side of the cooler, and the cooling fluid, usually water, flows through the shell side. The cooled sample then is taken to a laboratory for analysis or piped to in-line process instrumentation for continuous monitoring of properties such as conductivity, pH or other chemical constituents
-
The Sentry TSV is a self-contained, mechanical device that protects operators, analyzers and sampling components from high temperature liquids. It is an economical and reliable mechanical replacement for a solenoid shutoff valve and temperature controller, requiring no external source of electricity, air or hydraulics.
-
The Sentry high-temperature shut-off valve is designed for use with sampling systems to shut off flow when the sample temperature becomes too hot. The valve is suitable for grab sample or instrument applications that could experience a loss of coolant or surges in sample flow rates, which would cause the sample temperture to rise suddenly.
-
The Sentry W9000 Series sample coolers are designed for small volume hot water samples. The efficient counterflow design provides cooling for samples up to 750°F (399°C) and 3500 psig (241.3 barg), and the simplicity provides maximum cooling at minimal cost. With a compact design, simple installation and high quality materials, the W9000 Series sample coolers are the best low capacity option for small volume hot water samplers of water or other liquids.
