Flowmeter for Utility Gases: Proline t-mass 150

Everyone who depends on robust and cost-effective measuring technology for gas flows no longer has to put up with compromises. Whether for monitoring and controlling compressed air networks, for cost allocation, leak detection or use in energy management systems, the t‑mass 150 flowmeter, with its high turndown of up to 100:1, can reliably measure the smallest gas quantities even with very low operating pressures.

For compressed air, nitrogen, carbon dioxide and argon

Purpose of a Vent Hole in Pressure Sensors

Author: Michele Beyer (WIKA)
Posted: Knowledge

In so-called “gauge sensors” pressure is always measured relative to the currently prevailing ambient pressure. However, the ambient pressure is by no means constant. It is location-and height-dependent and changes with the weather. This means that for a “gauge” pressure sensor to operate, the (changing) ambient pressure must also be available inside the instrument. This means that the ambient pressure must be allowed to enter the instrument, i.e., the instrument must be “vented”. If an instrument of this type were to remain unvented, the change in weather and location, relative to the calibration performed by the manufacturer, an additional error up to several per cent would be introduced. This effect becomes of course less and less important with increasing pressure range of the sensor, compared with the actual change in ambient pressure.

By the way: in unvented instruments, the temperature influence adds another effect. Expansion of the air enclosed in the instrument as a result of a change in temperature causes a preliminary pressure, which also appears as an additional measuring error.

Conclusion: Pressure sensors used for measuring gauge pressure must be “vented”.

Typically, this is done via a controlled opening, a so-called vent hole. This vent hole must, of course, be carefully protected from the entry of dirt, dust and moisture. This can be supported by design measures (location, membranes, labyrinths, etc.) or must be ensured by the user on site by carefully controlling the mounting situation.

TURCK IP67-Rated, Eight-Port AIM Station for AS-interface Networks

TURCK introduces the new IP67-rated FAS8 Advanced I/O Module (AIM) station, the latest addition to the company’s line of AIM stations for AS-interface® (AS-i) networks.

TURCK introduces the new IP67-rated FAS8 Advanced I/O Module (AIM) station, the latest addition to the company’s line of AIM stations for AS-interface® (AS-i) networks. Previously only available in four-port configurations, the FAS8 provides users with an eight-port AIM station model.

The FAS8 station includes one digital PNP I/O signal per port, with an option for 2 Amp outputs. Providing the highest level of compatibility with industrial networking requirements, the station is designed to meet the latest AS-I V3.0 specification, allowing increased communication options for analog data and detailed diagnostic information.

Featuring PNP short-circuit protected inputs, the FAS8 automatically restricts current to prevent failures in the event of a sensor malfunction. Plus, through AS-i V3.0 specifications, users are quickly notified through a fault signal indication if there is a short-circuit on any I/O point. This module also supports both AS-I standard flat cable and round cable to accommodate current connection trends.

"While our customers liked the performance capabilities of the popular four-port AIM station, many were using splitters to access all I/O points," said Don Eichman, Product Specialist Networks at TURCK. "We responded with the development of the FAS8, allowing users to effectively meet their connectivity requirements."

The FAS8 station is fully encapsulated and potted, sealing it against environmental contaminants and eliminating the need for a separate enclosure for protection. With its durable construction and IP67 rating, the station is ideal for both indoor and outdoor applications—protecting against dust and moisture ingress to prevent performance failures in wet and dry environments.

TURCK is an industry leader providing superior quality sensing, connectivity and network products to help manufacturers improve their automated processes.
