Master gauges for pressure instrument testing, certification

When testing or certifying pressure monitoring devices, the calibration you perform is only as good as the master instrument you use for comparison. Ashcroft has carefully engineered the Type 1082 and 1084 test gauges for sustained accuracy and high reliability.

Available in 4.5-, 6- and 8.5-in. diameters, the Type 1082 boasts ±0.25%FS accuracy in ranges from vacuum through 10,000 psi. An external zero adjuster, temperature compensation and Monel wetted parts ensure precision and media compatibility. For field calibration, the 3-in. Type 1084 “pocket” test gauge is the smallest portable master gauge available, covering ranges to 1000 psi with 0.5% FS accuracy.

Pressure transmitters provide high accuracy

Toronto—Winters Instruments has announced its LLP Series Pressure Transmitter, designed specifically for use on applications that produce low pressures up to 25 psi. Featuring a 304 SS housing and 316L SS flexible diaphragm for pressure sensing, the LLP Transmitter is ideal for general industry use, as well as, OEM customers who require a high quality, high accuracy pressure transmitter.

Measuring 4” in height, this compact pressure transmitter is available in a wide range of mechanical and electrical connections. It is designed to detect low pressures in vacuum pumps and air compressors, monitor air filters, regulators and medical devices such as respirators, and is durable enough to withstand the requirements of mobile hydraulic equipment. The LLP is rated +/-0.5% accurate and may be used to measure ranges from 0/1 (28-in. H2O) psi to 25 psi.

To address environmental and health safety, the LLP Transmitter is RoHS certified (lead-free).

Pressure gages keep flutter to minimum

With recent double-digit rate increases in the price of Halocarbon oil, the cost of liquid filled gauges to measure the pressure of oxidizing agents has increased significantly. To avoid overspending, Ashcroft pressure gauges equipped with PLUS! Performance will eliminate the need for an expensive liquid fill while still controlling pointer flutter due to pulsation and vibration. The PLUS! option is available on a variety of Ashcroft pressure gauges, in a broad choice of service-types, sizes and configurations.
