Chemical and Plastics Industry

Chemical and Plastic Industry
The chemical industry uses processes such as chemical reactions on refining to produce a wide variety of solid, liquid, and gaseous material. These products can be used to manufacture other items, or can be used directly by consumers. We specialize in producing calibration and test equipment for use throughout the Chemical Industry. From digital test gauges and data recorders, to high accuracy dry block temperature calibrators, we have a variety of equipment to help you do your job.

General Calibration and Maintenance – Pressure gauges, pressure and temperature transmitters, transducers, electronic sensors, valves, regulators, and pressure and temperature switches need to be checked and calibrated periodically. The nVision offers multiple modules and special test modes for quick, easy verification. nVisionXP2i30 SeriesMTCCTCPTCASC-400

Temperature Sensors – Modernization in plants means that thermocouple and RTD sensors are used throughout in a variety of sizes and lengths. It wouldn’t be uncommon to see hundreds of sensors in a single plant. All of these sensors must be calibrated once or more a year, depending on accuracy class. Previously, sensors were calibrated in oil baths, or large heating ovens, but due to complicated and slow testing procedures, limited temperature ranges, and hazardous liquids, dry-block calibrators are replacing them with clean, quick, accurate instruments. The JOFRA line of dry-block calibrators offer a variety of temperature calibration equipment to calibrate these sensors. Dry-Block Calibrators

Transmitter/Flow Computer Calibration and Validation – Static and differential pressures, along with temperature are commonly measured to calculate flow, using transmitters and flow computers. Calibration and validation is needed to assure their accuracy. The nVision allows a user to complete pressure calibration and validation of a differential transmitter, our temperature calibrators calibrate the temperature component, and our ASC-400 simulate the signal to the flow computer. nVisionTemperature Calibrators

Datalogging/Data Recording – Record pressure, temperature, current, and voltage at up to 10 readings per second using the nVision. The battery-optimizing, Ultra Low Power (ULP) mode, allows an entire year of continuous recordings on one set of batteries. nVision, XP2i

Relief Valve and Rupture Disc Testing – Pressure safety valves and rupture discs protect pressure vessels and piping systems from excessive internal pressure. Periodic testing and adjustment of this equipment is essential to maintain overall safety. Our equipment catches the maximum pressure at high speeds (up to 10 readings per second) to complete and document the tests. nVision, HPC40, XP2i

Tank Level (Storage) – Producers store their inventory in holding tanks, and an accurate pressure and temperature measurement of each storage vessel creates a record of their inventory on-hand. The nVision offers an easy and fast way to record accurate pressure measurements and the RTC measures and calibrates temperature. nVision, HPC40, XP2i, RTC

Pump Testing – The nVision monitors inlet and outlet pressures and records from two pressure sensors, up to 15 000 psi, as fast as 10 times per second, to characterize the pump. nVision, HPC40, ASC-400 with APM

Hydrostatic Testing/Leak Testing – Pressure systems are tested for their strength and leaks by pressurizing a liquid, and observing whether there is a pressure loss. Both the XP2i and nVision record the pressure test producing a digital record. Pressure and temperature can be recorded simultaneously by using the nVision. nVisionHPC40XP2i

Filter Testing – The nVision can measure and record differential pressure at high static pressure directly across a filter. By estimating a filter's relative age and wear in this manner, a customer can save money by only replacing filters when needed. nVision, HPC40

Deadweight Tester Replacement-Augment – The nVision offers the accuracy of a deadweight tester in a much lighter and more portable package. It is also unaffected by temperature or gravity, requires no special training, and is less expensive to calibrate. nVision, HPC40

Direct Pressure Measurement – Various places throughout oil & gas facilities will require direct measurement of pressure. This could involve permanently mounting an instrument or completed periodic checks. Our intrinsically safe instrumentation provides the flexibility and accuracy to confidently measure pressure. nVision, XP2i, HPC40, 30 Series, ASC-400 with APM

Barometric Pressure Measurement – Some applications, such as calibrating absolute pressure gauges, will require the reference gauge to read directly in barometric pressure. The nVision, with the optional barometric reference will indicate pressure in the absolute scale. You can even toggle between gauge and absolute pressure on the same device. nVision, HPC40, ASC-400 with APM

Maintenance of Calibration Standards and Test Equipment - Portable calibrators and test equipment requires periodic checks and calibration. Having local standards on site for calibration of these instruments offers a savings in cost and downtime of instruments: calibrate the field instruments locally and then send only the standard in for regular calibration. The nVision and HPC40 Series are small, light-weight instruments that have the accuracy required to calibrate pressure in the field or in a lab. The DTI Series with an STS may be used as high accuracy temperature references. The RTC and PTC series are excellent standards for the verification and calibration of handheld thermometers. There is no better pressure standard than a deadweight tester for calibrating pressure instruments and our deadweight testers are designed to be highly accurate but durable. nVision, HPC40, DTI, APM CPF, RTC, PTC, Deadweight Testers, ASC-400 with APM
