New Dual-Range Pressure Calibrator for Gas Custody Transfer Measurements in Intrinsically Safe Environments

Fluke (UK) has introduced a new ‘Ex’ Dual Range Pressure Calibrator for use in classified environments, offering ranges, accuracies and capabilities that make it ideal for gas custody transfer measurements. The new Fluke 721Ex, with IECEx and Atex Ex ia IIB T3 Gb (Zone 1) ratings, is available in 14 models and can be used with a Fluke 720RTD probe for temperature measurement. Fluke has also introduced 700 series pressure test hose and pump kits which minimise the difficulty and leaks when connecting a pressure calibrator or pump to a device under test. Their quick installation, without the use of tools, increases efficiency, saving time and money. These pressure accessories are a best-in-class set of premium hose and No Tools Required (NTR) pressure connection accessories.

The rugged Fluke 721Ex Dual Range Pressure Calibrator, featuring two isolated, stainless steel, pressure sensors with accuracies to ±0.025% Full Scale, provides measurement of static pressure, difference in pressure and (optional) temperature of gas flow. The Fluke 721Ex is configured by choosing either a 1.1bar or 2.48bar low-pressure sensor, together with one from seven high-pressure ranges, including 6.9, 20, 24.5, 69, 103.4, 200, or 345 bar. The large backlit display will show two pressure readings and a temperature reading simultaneously. Up to five frequently used setups can be stored.

Fluke 700 Pressure Calibration Test Kits introduce a new family of pressure connection accessories to make the difficult task of making pneumatic and hydraulic pressure test connections easy and leak free. This family of accessories includes two special transmitter test hoses, the TTH5K and the TTH10K, providing No Tools Required connections between hand pumps or pressure transmitter to the standard IEC ¼" female input on most pressure transmitters worldwide. The 700MTH test hose is similar to the 700TTH but has a ¼" male metric hose termination rather than the ¼" NPT male connection. The 700M20TH is intended for connection to female Chinese M20 process connections.

The new 700PTPK2 Pneumatic Test Pressure Kit and 700HTPK2 Hydraulic Test Pressure Kit are premium versions of the standard 700PTPK and 700HTPK and add premium test hoses and a NTR connection to easily attach and remove 700G test gauges or other devices with ¼" NPT male terminations.

The Fluke 721Ex is supplied with a soft case offering storage for an RTD probe.
