Introduction

The TH-144U is an advanced digital panel meter that is specifically designed for industrial, aerospace, and automotive applications. This highly sophisticated, yet sophisticatedly simple, multipurpose panel meter certainly lives up to its motto of being the ultimate in accuracy, ruggedness, and ease of installation. The versatility and ease of programming the TH-144U make it ideally suited for numerous industrial applications.

TH-144U Application Field and Working Principle

The TH-144U is a multi-functional digital panel meter capable of displaying and collecting data in a number of formats, such as digital, analog, counter, hour meter, and numeric. This makes the TH-144U suitable for a wide variety of industrial applications, such as monitoring cumulative engine hours, hours for a given cycle, engine or machine run time, manufacturing processes, or a myriad of other tasks.The TH-144U panel meter is powered via a low voltage DC supply and is capable of running on anything from 12-24 VDC. It is designed to be mounted on almost any type of panel, be it horizontal or vertical, and can even accept isolated input signals.The TH-144U has a number of features that help it to work reliably even in harsh or difficult conditions, such as its high level of protection against dust, dirt, and moisture. It also features a safety filter and latching relay protection to help ensure accuracy and reliable operation.The working principle of the TH-144U is based on the use of a variable frequency digital clock, which is synchronized with a selected frequency source, such as a quartz clock, a power line, or a time pulse. The device then uses this to create a digital time count that can be interpreted by users. The time count can be derived from manual input or determined from an electronic display readout.The readouts produced by the TH-144U are quite accurate, and range from 1/125 second to 5,000 days depending on the mode selected. The output count can be expressed in any of a number of formats, including minutes, seconds, hours, days, weeks, and even months.The TH-144U is also equipped with four programmable modes that allow users to tailor the TH-144U to their specific application needs. For example, the Device Control mode enables the user to program the TH-144U so that it can act as an automated switch or control system. The Meter Reading mode allows the panel meter to display the real-time reading of any connected analog signal. Alternatively, the Meter Reset mode enables the TH-144U to monitor signal changes and reset the time count accordingly.In addition, the TH-144U also provides communication capabilities via its integrated RS-232 and RS-485 ports. This allows users to monitor and control the device from a remote location.

Conclusion

The TH-144U is a reliable and versatile digital panel meter that is specifically designed for industrial, aerospace, and automotive applications. Its highly accurate readouts are derived from a variable frequency digital clock and can be tailored to suit specific requirements via its four programmable modes. Additionally, its remote communication capabilities enable users to monitor and control the device from a remote location. This makes TH-144U an ideal choice for any type of industrial application that requires an accurate and dependable digital panel meter.
