Valcom T7T SMART Temperature Transmitter

Valcom T7T SMART Temperature Transmitter

The Valcom T7T SMART Temperature Transmitter combines a 4-20 mA output and HART® digital communication protocol, making it compatible with 3-wire resistance thermometers. This electronic transmitter is specifically designed for Pt 100 ohm resistance thermometers, with its accuracy dependent on the class of sensors used (e.g., DIN A, DIN B, 1/4 DIN, 1/10 DIN, etc.). With its ATEX certification, the Valcom T7T Transmitter can be directly installed in hazardous areas, providing reliable temperature monitoring. The transmitter offers flexibility in configuration and adjustment, allowing for local changes through its push buttons and display, or remote adjustments using HART® protocol compatible communicators.

The T7T series is a range of smart electronic transmitters featuring a 4-20 mA output and HART® digital communication protocol. Whether you need to make on-site modifications or remote adjustments, this transmitter offers the convenience of both options. It can be easily mounted on a pipe or tank, with or without a thermowell. For installations requiring a remote sensor, the Valcom T7T Transmitter includes a supplied bracket for wall mounting or a 2″ stand pipe mounting option. This enhances the versatility and adaptability of the transmitter for various application needs. The transmitter holds a marine type approval, certifying its suitability for marine applications. This approval confirms that the T7T meets the applicable requirements of the RINA type approval system, ensuring its reliability and performance in marine environments.

The Valcom T7T SMART Temperature Transmitter is an advanced and versatile device designed to accurately measure and transmit temperature data. With its impressive range of features and specifications, this transmitter offers reliable performance and seamless integration into various industrial applications. One of the key aspects of the T7T transmitter is its wide operating voltage range, which allows it to be powered by a supply voltage between 12.5 and 30 Vdc. This flexibility enables easy integration with existing power systems and ensures reliable operation in different environments.

The T7T transmitter provides an output signal of 4-20 mA, which is a widely used standard in industrial applications. Additionally, it features Hart® Rev6 compatibility, enabling communication and control capabilities through the Hart® protocol. This capability opens up possibilities for remote configuration, diagnostics, and calibration, enhancing the overall functionality and ease of use. To facilitate effective monitoring and control, the transmitter offers alarm functionality with pre-set values. The alarm values can be configured to trigger when the measured temperature reaches or exceeds 3.85 mA or 21 mA, providing immediate notification of critical temperature conditions.

The device is designed to handle varying loads, and the maximum load specifications are provided in a chart. For Hart® operation, the load resistance (RL) should be between 220 Ω and 600 Ω. This allows for flexibility in the choice of load resistance, ensuring compatibility and optimized performance. Furthermore, the device offers damping functionality, allowing users to adjust the response time to match specific requirements. With a damping range of 0 to 60 seconds, it provides flexibility in tailoring the transmitter’s response to meet specific application needs.

Long-term stability is a crucial aspect of temperature measurement, and the T7T transmitter excels in this regard. It exhibits stability within 0.1% FS per year, ensuring accurate and reliable temperature measurements over extended periods of operation.

The T7T transmitter incorporates a clear LCD display that can operate within a temperature range of -10°C to +65°C. This feature ensures visibility and readability of temperature measurements, even in varying ambient temperatures. For protection against external elements, the transmitter is available in two housing options: AISI 316 stainless steel (IP67 protection) or aluminum (IP66 protection). These robust housings provide reliable ingress protection, safeguarding the device from dust, moisture, and other environmental factors.

To ensure its durability and reliability, the T7T transmitter has undergone vibration testing in accordance with IEC 60068-2-6 standards. This testing guarantees its ability to withstand vibrations typically encountered in industrial environments. The transmitter is designed to operate in relative humidity levels below 98% without condensation. This feature ensures stable performance and accurate temperature measurements even in humid conditions.

In terms of certifications and approvals, the T7T transmitter complies with various industry standards and directives. It meets the requirements of Directive 2014/34/EU (ATEX) for explosive atmospheres, ensuring its safe operation in such environments. Additionally, it complies with Directive 2014/68/EU (PED) for pressure equipment and Directive 2014/30/EU (EMC) for electromagnetic compatibility. These certifications validate the transmitter’s adherence to stringent safety and quality standards. Furthermore, the T7T transmitter has achieved SIL2 certification, ensuring its compliance with functional safety requirements. It demonstrates a high safety integrity level, making it suitable for critical applications that demand reliable and fail-safe operation.

In summary, the Valcom T7T SMART Temperature Transmitter combines advanced technology, high accuracy, and robust construction to deliver precise temperature measurements in various industrial applications. With its wide operating range, compatibility with standard communication protocols, and comprehensive certifications, the T7T transmitter is a reliable and versatile solution for temperature monitoring and control.
