1646 Compact Digital Pressure Transmission Controller
Introduction: The principle and structure of the 1646 compact digital pressure transmission controller. The 1646 digital pressure transmission control
Product details
Principle and Structure of 1646 Compact Digital Display Pressure Transmission Controller
The 1646 digital pressure transmission controller is a fully digital measurement and control product that integrates pressure measurement, display, contact control, and transmission output. It can be directly installed at the on-site pressure measurement point, and various parameters such as zero point, full-scale value, contact pressure, and control pressure can be set on-site using buttons.
1646 Compact Digital Pressure Transmission Controller
Application of 1646 Compact Digital Display Pressure Transmission Controller
Non corrosive gas and liquid pressure measurement for 316 stainless steel
Applied to industrial process sites such as petroleum, chemical, metallurgical, power, hydrology, etc
Features of 1646 Compact Digital Pressure Transmission Controller
Wide measurement range, explosion-proof shell, all stainless steel structure, diverse pressure interface forms, ultra bright LED pressure display
Up to two relays or electronic switches can be provided, with arbitrary settings for contact values and contact states, ensuring precise and reliable control
The intrinsically safe explosion-proof product meets the requirements of national explosion-proof standards and has obtained an explosion-proof certificate with the explosion-proof mark Exia Ⅱ CT6
