DPT2090-100G Johnson Controls Pressure Transmitter

Overview

The Johnson Controls DPT2090-100G is a high-performance gauge pressure transducer designed to sense pressure and convert it into a proportional high-level analog voltage signal. Engineered for demanding commercial and industrial HVACR and building automation applications, it integrates seamlessly into controllers, building management systems, chillers, boilers, and refrigeration plant management systems. Featuring a rugged stainless steel capacitance sensing element, this unit delivers exceptional accuracy, long-term stability, and reliable performance even in harsh environments or high-vibration applications.

Features

• Premium Capacitive Sensing: Employs a trusted, dead-ended variable capacitor design using a 17-4 PH stainless steel sensor for maximum reliability with no additional amplification required.
• Rugged Construction: Housed in a durable stainless steel and Valox enclosure designed to withstand high shock and vibration without any internal seals or O-rings that could cause leakage.
• Broad Environmental Tolerance: Features a wide operating temperature band, making it well-suited for extreme process and ambient conditions.
• Standardized Signal Offset: Provides a precise analog voltage curve ideal for modern DDC controllers and proprietary systems requiring diagnostic offsets.
• Convenient Installation: Equipped with a pre-wired 2-foot multi-conductor cable for straightforward electrical terminations and an integrated 1/4-inch NPT pressure fitting.
