Honeywell STD810 Differential Pressure Transmitter

1.General Description

The Honeywell STD810 Differential Pressure Transmitter is a high-quality device. It measures differential pressure accurately in many industrial and important process applications. std810 includes only zero shift with static pressure

Part of the SmartLine® family, the STD810 SmartLine Differential Pressure Transmitter offers advanced piezoresistive sensor technology combined with integrated temperature and static pressure compensation. The transmitter includes zero shift with static pressure functionality to ensure consistent accuracy under changing operating conditions.

The STD810 offers a rangeability of up to 100:1 and an accuracy of 0.035%. It meets the high demands for pressure measurement. This includes uses in custody transfer and energy management.

The team tested the system completely. They made sure it works well with Experion® PKS. This ensures smooth integration with Honeywell process control systems.

Its tough design and smart technology make it great for important tasks. It meets FM Explosion Proof, Intrinsically Safe, Non-incendive, and Dustproof standards. This ensures high reliability and safety for valuable applications.

5.Honeywell STD810 Installation Procedure

A. Preparation:

 Configure the transmitter for its intended process measurement environment, considering static pressure and temperature conditions.

B. Mounting:

 Install the transmitter in a vibration-free, moderate-temperature area using appropriate process connections (e.g., 1/2" NPT or flange).

C. Wiring:

 Connect the differential pressure transmitter to the control system via the specified output (4–20mA, HART®, etc.). The polarity-insensitive design simplifies installation.

D. Configuration:

 Use the local display or configuration tools to adjust parameters such as zero, span, and damping.

E. Testing:

 Apply known pressure differentials to verify the transmitter’s output accuracy and performance under static pressure conditions.
