Calibration of “impossible” Temperature Sensors Made Easier

RTC-168 Dry Block Calibrator from JOFRA Calibration We are pleased to announce the new JOFRA RTC-168 Series. It offers more flexibility, better accuracy, more stability, and faster speed. JOFRA's 3rd generation dry/wet combination calibrator from JOFRA - based on know-how! New Liquid System - A redesigned liquid basket and a faster magnetic stirrer have resulted in a longer temperature uniformity zone. This vertically extended uniformity zone now makes it easier for smaller sensors, like sanitary sensors, to reach the uniformity zone resulting in improved calibrations. In addition, more space is now available to…Read more

Cameron Instruments Service & Return Process

As a trusted calibration and service partner we often get questions about our calibration and repair process. This prompted us to put together an RMA (Return Merchandise Authorization) Instructions page with answers to some frequently asked questions. I've compiled these thoughts here to hopefully make the process clear and easy to follow. First Steps The first step in returning anything to us is to complete our online RMA Form. This form can be accessed on our home page: by clicking on the RMA Form button. By filling out the form you are…Read more

Choosing a Gauge: Gauge Construction

When you know what to look for, you can tell in advance which gauges can stand up to the elements you work in. Sensors: Welded Sensor: It's not generally possible to tell whether a sensor is fully welded by looking at the gauge, so check with the manufacturer. Non-welded sensors use o-rings or even thread tape inside the gauge. O-rings can degrade, and both o-rings and thread tape have the potential for leaks. Moisture: If the specification warns you to use clean, dry air, the sensor does not have an isolating diaphragm. It…Read more

Replacing Outdated Calibration Equipment in Peaking Power Plants

A local peaking power plant with four combustion turbines was looking to replace some older pressure calibrators for their instrumentation and control technicians. These instruments would calibrate gauges, sensors, and transmitters for parameters such as steam pressure, differential pressures for level and flow, fuel pressures and more. The team was looking to replace basic pressure calibrators. The AMETEK Solution The AMETEK HPC40 Series with a 30 psi low-pressure sensor and a 3000psi high-pressure sensor was determined to be a good fit for the applications that they had described. The dual range calibrator allowed…Read more

Cameron Instruments Inc., Laboratory Expansion

Cameron Instruments Inc. operates a state-of-the-art ISO 17025 accredited pressure calibration facility.  Their laboratory provides high accuracy pressure and temperature calibrations, using Fluke Piston Gauges and AMETEK JOFRA dry block and liquid bath temperature calibrators.  Their current scope for pressure provides coverage from 5kPa (0.7 psia) to 200 MPa (30,000 psia) in either gauge or absolute mode.  Their temperature capabilities cover an effective temperature range from   -100°C to +660°C.  Over the past year, Cameron Instruments has invested in their laboratory by adding three key pieces of equipment.  The purpose of these additions was…Read more

New Connection Wizard in the AMETEK ASC-400 Multifunction Process Calibrator

Process signals are crucial, from controlling valves, switches, or lights to measuring pressure in a pipe to calibrating temperature in a bakery oven. Ensuring that these process signals remain accurate is essential. Users have multiple choices on the calibration equipment they use. One of the most important factors to consider is ease-of-use. Since multiple process signals may be used, including; volts, millivolts, amps or milliamps, and each of these may have large range differences, most users turn to a multi-function calibrator to satisfy all situations. However, as the options increase, the instruments complexity…Read more

Aircraft Pressure Transducer Calibration: How to increase accuracy and significantly cut labour time with automation

In aerospace applications, pressure transducers and switches play critical roles in monitoring many systems through out the aircraft - from hydraulics and electromechanical systems to avionics. Breaking, propulsion, wing flap control, cabin pressure and countless other functions rely on pressure transducers and switches to ensure that the process is happening correctly. Accuracy is critical. Because these devices are constantly subjected to extreme vibration, frequent ambient temperature changes, and shock, regular calibration is essential to ensure accurate performance. Traditionally, many FAA-approved repair centers perform aircraft calibration with a hydraulic test media, manual screw press…Read more

Controlling Temperature in the Delivery of COVID-19 Vaccines

Using the RTC-159 to calibrate the sensors used during storage and transport of COVID-19 Vaccines Pharmaceutical companies all over the world are diligently working overtime to produce an accepted COVID-19 vaccine. While this work continues, other companies are already planning how to distribute a potential vaccine. Perhaps the most significant challenge exists in temperature control as some COVID019 vaccine candidates will require ultra-low temperatures (ULT), typically ranging from -86°C to -45°C. For COVID-19 vaccines requiring ULTs, maintaining these freezing temperatures throughout the process, from manufacturing to delivery to patients, is necessary. Failure at…Read more

New High Range Ozone Sensor for Ozone Sterilization Applications

Published on September 7, 2020 Written By: St John Vuetilovoni, Product Manager HH/AQY at Aeroqual Ltd. WHAT APPLICATIONS IS THE HIGH-RANGE OZONE SENSOR FOR? Ozone sterilization is commonly used in hospitals to sanitize equipment and significantly reduce or eliminate the spread of bacteria. In addition, ozone sterilization applications are emerging where time is a constraint and therefore a higher dosage of ozone may be required to reduce the sterilization time while still achieving efficacy. An example of sterilization of public transport where vehicles such as buses and trains use ozone treatment to achieve…Read more
