PR Electronics High Accuracy Temperature Transmitter 35V dc, -40 °C to 60 °C Operating Temperature 6335A2A

PR Electronics 6335A2A Temperature Transmitter is a highly accurate 2-wire HART compatible device operating at 35V dc with an operating temperature range of -40 °C to 60 °C. It is designed to convert various temperature sensor inputs including thermocouples and RTDs to a standardized 4 - 20 mA output signal, suitable for demanding industrial process control applications.

This transmitter offers exceptional input versatility, supporting a minimum temperature input of -200 °C and a maximum of 850 °C, effectively covering a broad range of temperature measurement scenarios. Its galvanic isolation of up to 1.5 kVAC ensures electrical separation between input and output for enhanced operational safety and signal integrity.

The unit features sensor redundancy capabilities which ensure continuous process availability by switching to backup sensors automatically if the primary sensor fails. Its DIN Rail mounting enables straightforward and secure installation within industrial control panels.

The transmitter demonstrates superior immunity to conducted noise, being tested against 10 Vrms in frequencies from 15 Hz to 100 MHz, reducing the risk of signal distortion in electrically noisy environments. It complies with international hazardous area certifications such as ATEX Zone 2 and safety standards including UL 61010/508 and IEC 61508 full assessment, making it suitable for use in hazardous industrial environments.

Configuration and calibration are streamlined via the free PReset software, which allows quick setup of input parameters, output modes, sensor error detection, and process calibration through standard PC interfaces, ensuring tailored operation for specific process needs.

Typical industrial applications include process control in chemical, manufacturing, HVAC, water treatment, and energy sectors where reliable and precise temperature measurement is critical. This transmitter also logs runtime metrics and monitors ambient temperatures to enhance safety and diagnostics.
