Pressure Measurement & Control
Digigauge digital pressure gauges from Dresser Instruments boast exclusive features not found elsewhere. The gauges are packed with options and include the ability to be customised for customers' exact application requirements. This new product line has three Ashcroft digital gauge models: the Ashcroft precision digital, the industrial digital, and the general-purpose digital.
The Ashcroft Type 2089 precision digital gauge is an award-winning product with accuracy specifications of ±0,05% full-scale total error band including linearity, repeatability, hysteresis and compensated temperature from 0° to 150°F (-18 to 66°C). It is rugged, portable, easy-to-read, and combines precision and multifunction capability in a weatherproof case. The unit boasts seven-language capability and is FM approved for intrinsically safe operations, Class 1, Division 1. Other precision digital products are available in the Type 2080 Series.
The new Ashcroft Type 2274 industrial digital gauge introduces the distinguishing features of 4-20 mA output and a switching option of one or two SPDT switches. This product combines local indication, transmission and switching capability into one durable and economical package. All products in the Ashcroft 2074 Series offer the exclusive Ashcroft AccuSeal option; an unconventional diaphragm seal design that uses the sensor diaphragm to keep the media from clogging the gauge. This gauge/seal combination has a terminal point full-scale accuracy of ±0,25%.
The Ashcroft Type D1005PS general-purpose digital gauge has ±0,5% full scale, terminal point accuracy including linearity, repeatability and hysteresis. Unlike competitors' products, this accuracy statement is not 'typical' but applies to every unit and its 4,5 digit display provides the resolution needed to read the stated accuracy. The gauge has nine selectable units of measure; offers pressure ranges from vacuum through 19 999 psi (138 MPa) plus compound ranges; and has a ½" character size for easy reading. The unit is CE approved and is offered with a ±0,25% full-scale accuracy option.
