Honeywell STG77S transmitter is its superior high-frequency anti-vibration and high anti-interference performance. Through advanced digital signal processing technology, errors caused by vibration, temperature and other environmental factors are eliminated. This makes it have extremely high measurement accuracy and stability; at the same time, its wide application range makes it suitable for various complex working environments.

1. High precision and long-term stability:  can provide high-precision measurement results (accuracy is ±0.065 percent ), and its long service life has good long-term stability, allowing continuous and reliable operation.

2. Sensitivity adjustment function:  can automatically adapt to environmental changes, such as climate fluctuations. Zero and span adjustments can be made as needed to ensure the accuracy of the measurement results.

3. Digital communication: has HART communication protocol, which can realize digital communication, allowing users to monitor and remotely configure the transmitter in real time.

4. Abundant diagnostic functions: With self-diagnostic function, it can send fault alarms to operators to help solve problems in time and reduce losses caused by equipment faults.

5. Material and design: Honeywell STG77S transmitter adopts materials with high corrosion resistance and protection level, which can effectively resist adverse environmental factors in various external environments and application fields.

6. Multiple installation methods:  supports many different installation methods, such as wall-mounted, pipe-mounted, etc., suitable for different process conditions and installation environments.

The STG77S transmitter has a variety of output options, and can provide current signals (4-20mA), digital signals (HART protocol), combined signals, etc. according to the actual needs of the site. In addition, this transmitter also has a MODBUS output option to communicate with the monitoring or control system through the 485 bus to achieve remote monitoring and data management.

Honeywell STG77S transmitter has a high protection level, its shell is made of stainless steel, and adopts laser welding technology to ensure good sealing performance, excellent corrosion resistance and strong adaptability. Its protection level reaches IP67, which can withstand the erosion and impact of harsh environments for a long time.

1. Accuracy up to 0.065 percent of calibrated span

2. Stability up to 0.025 percent of URLs per year for five years

3. Automatic temperature compensation

4. Rangeability up to 100:1

5. Response times as fast as 100ms

6. Easy to use and intuitive display capabilities

7. Intuitive External zero & span capability

8. On-board diagnostic capabilities

9. Integral Dual Seal design for safety based on ANSI/NFPA 70-202 and ANSI/ISA 12.27.0

10. Full compliance with SIL 2/3 requirements as a standard

Honeywell STG77S transmitter can easily replace similar products. At the same time, it has a wide range ratio (maximum 100:1) and over-range protection function, which makes it have higher use value. During on-site installation and commissioning, the STG77S transmitter has the advantages of easy operation and high flexibility. It can directly adjust the zero point and span on site, and can also perform parameter setting and diagnosis through a HART handheld operator. At the same time, it also has a self-diagnosis function. When an abnormal situation occurs, it can be reported to the police in time, which is convenient for users to maintain and deal with.
