1、 Product details:
Agreement with Rosemount 3144P HART temperature transmitter with superior accuracy, stability and reliability, making it a control / security applications in the industry-leading temperature transmitter. Rosemount 3144P has the support of a single sensor input and the dual capacity of dual-sensor input. Dual sensor input capability allows the transmitter to the sensor simultaneously from two independent receiver input signal. Dual-sensor configuration can be used to measure temperature, average temperature or for redundant temperature measurement.Used to control / security of the optimal temperature transmitter A transmitter also has support for single sensor and dual sensor capabilities
Enhance the ability of anti-EMI and filter measurements in the process to ensure excellent stability
Safety Instrumented Systems by IEC61508 (SIS) of the third-party measurement certification
Industry-leading 5-year stability and reduce maintenance costs
Hot Backup ? and sensor drift warning feature can improve the measurement of long-term reliability
Match the transmitter and sensor interchangeability of the sensor to eliminate errors, improve the measurement accuracy of 75%
Even in the harsh environment, the two-chamber housing also ensures the highest reliability
Integration of the large LCD meter display, easy reading
