Product Description

The STD725-E1HK2AS-1-A-AHT-11S-A-30A6-FX.F3.TP.PM-0000 is a high-performance differential pressure transmitter from Honeywell's SmartLine series. Designed for industrial applications requiring precise pressure measurements, it features a 316L stainless steel wetted material and silicone oil fill fluid, ensuring durability and chemical compatibility. The transmitter offers a wide turndown ratio of 100:1, allowing for versatile range capabilities. It supports both analog (4–20 mA) and digital (HART® 7.0) outputs, facilitating integration with various control systems. With an accuracy of up to 0.065% of the calibrated span and a stability of 0.020% of URL per year over 10 years, it ensures reliable and consistent performance. The device is housed in a polyester powder-coated aluminum enclosure, providing protection against environmental factors. Additionally, it complies with SIL 2/3 safety requirements, making it suitable for critical applications in process industries.
