DM670TM digital display

Description

The DM670TM digital display is designed to accept RTD or thermocouple temperature sensors and display the sensor temperature in °C or °F on a 6-digit LCD display.

This innovative instrument allows the display of one or two (1 to 32) character messages. The user can select an alert event that is triggered when the temperature is within a certain range.

With two switching relays operating independently, the user can perform the switching at points defined by the user, in combination with messages and warnings. In addition, a data logging function is available to record process details up to 5000 points.

Important features include:

• Double relays: the instrument is equipped with 2 relays of the switching type, which operate independently. The user can select one of seven actions, including deviation, lock or no-lock, and adjust the point and hysteresis settings. The relays can be switched off when they are not needed, extending battery life.
• Data logging function: the DM670TM offers a powerful data logging function. Up to 5000 logging points can be configured, each with a time and date stamp, temperature and relay status information. The recording speed is flexible and it is also possible to make fixed or rolling records.
• Battery power: the instrument runs on one 3.6 V lithium battery. Battery life depends on active functions such as relays and warning LEDs. The expected battery life is at least 1 year (longer depending on the options chosen).
• Real-time schedule: date and time stamped maximum, minimum and average temperature values, as well as relay on/off information, are recorded and can be displayed together with the current time and date. The real timer is also used to record the points of the recorded data.

 

Who is the DM670TM suitable for?

• Industrial companies: the instrument is suitable for industrial applications where precise temperature monitoring and the use of relays for switching operations are required. This includes sectors such as manufacturing, process industries, chemicals, food and pharmaceuticals.
• Automation engineers: the DM670TM offers advanced features and relay switching, which is important in automation systems. Engineers can use the instrument to monitor and control temperature parameters in various automated processes.
• Technical maintenance personnel: its ease of use makes the DM670TM suitable for technical maintenance personnel who are responsible for monitoring temperature data and performing switching operations. The ability to record data allows long-term trends and patterns to be tracked and analysed.
• Laboratories: the DM670TM is useful in laboratory environments where accurate temperature measurement and data logging are required. With the ability to display messages, the instrument can provide important information or warnings to laboratory staff.
• Research institutions:The DM670TM is a useful instrument where data collection and recording of temperature changes is required. Its relay switching capability allows it to operate automatically when a certain temperature is reached.
