| High Light | 644 Temperature Transmitter ，Dual Sensor HART Head Mount ，SIL 3 IEC 61508 Certified | ||
The 644 Temperature Transmitter is the most versatile temperature transmitter family, designed to reduce complexity and simplify the day-to-day operations of diverse temperature measurement applications. With new and easy-to-use capabilities including advanced diagnostics, safety certification, integral transient protection, and flexible display options, the 644 helps you make better decisions for your process.
Single or dual sensor input versions are available for RTD, thermocouple, mV, and ohm inputs. The dual sensor head mount (model code S) and field mount (model code D) versions support HART protocol, while single sensor versions (model code H) are available with HART, FOUNDATION Fieldbus, or PROFIBUS PA output.
Newly shipped devices include a unique QR code asset tag that enables access to serialized information directly from the device, including device drawings, diagrams, technical documentation, and troubleshooting information. This improves mean time to repair, maintains efficiency, and eliminates the time-consuming process of locating and transcribing nameplates.
The 644 is available with a wide range of hazardous location certifications including ATEX, IECEx, CSA, FM (USA), China Ex (Intrinsic Safety, Flameproof, Type n), INMETRO, Japan, EAC, and Korea approvals.
