Product Description

Product Description

Product Overview

The Honeywell ST700 Pressure Transmitter is a state-of-the-art instrument designed for precise and reliable pressure measurement across a wide range of industrial applications. Engineered with advanced sensor technology and robust construction, the ST700 excels in environments requiring high accuracy, stability, and durability. It supports measurements for absolute, gauge, and differential pressure, making it versatile for industries such as oil and gas, chemical processing, water treatment, and HVAC systems. The transmitter features a modular design, allowing customization through configurable options like output signals (4–20 mA HART, FOUNDATION Fieldbus, or PROFIBUS PA), materials of construction (e.g., 316L stainless steel, Hastelloy), and pressure ranges from vacuum to 10,000 psi. Its compact, lightweight housing ensures easy installation in space-constrained areas, while IP68/NEMA 6P environmental protection and compliance with global standards (IEC, ATEX, SIL) make it suitable for harsh or hazardous conditions. 

Key Advantages

The ST700 stands out for its exceptional accuracy (±0.04% of span) and long-term stability, achieved through Honeywell's proprietary Sensor Technology (HST), which minimizes drift caused by temperature fluctuations and mechanical stress. Its advanced sensing element, combined with digital signal processing, ensures reliable performance even in dynamic process conditions. The transmitter's intuitive interface with a local LCD display simplifies configuration, calibration, and troubleshooting, reducing downtime and training costs. Additionally, the ST700's robust design includes a hermetically sealed electronics compartment and anti-clogging isolators, enhancing reliability in corrosive or particulate-laden environments. The device also supports wireless connectivity options, enabling seamless integration into Industrial Internet of Things (IIoT) ecosystems for remote monitoring and data-driven decision-making. With a focus on energy efficiency, the ST700 consumes minimal power while delivering high-resolution outputs, aligning with sustainability goals.

Step	Procedure	Details
1	Mount the transmitter	Install on a stable surface or pipeline using appropriate brackets. Ensure process connection matches the media.
2	Electrical connections	Connect power supply (10.5-42 V DC) to terminals +ve (pin 1) and -ve (pin 2). Use shielded cable for signal lines.
3	Apply pressure	Slowly introduce process pressure to avoid shock. Verify pressure limits (0-100% of calibrated range).
4	Configuration	Use HART communicator (HT3x) to set parameters: range, units, damping, output linear/square root.
5	Calibration	Perform zero and span calibration via HART menu: "Sensor Trim" -> "Zero Trim" / "Span Trim".
6	Output verification	Check 4-20 mA output corresponds to applied pressure using multimeter or control system.
7	Seal adjustment	Apply thread sealant to NPT connections. Torque wrench to 15-20 Nm for ½" NPT threads.
8	Loop test	Simulate 0%/50%/100% pressures and validate control system responses.
9	Maintenance	Perform annual recalibration. Clean diaphragm with isopropyl alcohol if contaminated.

Application Flexibility and Industry Leadership

Honeywell's ST700 Pressure Transmitter is a market leader due to its adaptability and proven performance in critical applications. Its ability to handle extreme temperatures (-40°C to 85°C) and aggressive media makes it ideal for offshore platforms, refinery processes, and pharmaceutical manufacturing. The transmitter's global certifications (e.g., SIL 2/3, CE, FM, CSA) ensure compliance with stringent safety and regulatory requirements. Furthermore, Honeywell's global support network provides comprehensive services, from installation to lifecycle management, ensuring maximum uptime. By combining cutting-edge technology with user-centric design, the ST700 reduces total cost of ownership through extended calibration intervals, reduced maintenance needs, and interoperability with legacy systems. This blend of precision, durability, and innovation solidifies the ST700 as a trusted solution for industries demanding uncompromising measurement performance and operational resilience.
