Setra Systems 231G-MS2-3V-D Multi-Range Differential Pressure Transducer with LCD Display

The Setra Systems Model 231G-MS2-3V-D is a wet-to-wet, multi-configurable differential pressure transducer designed for monitoring pumps and load differential pressures in HVAC systems, Building Automation Systems (BAS), and industrial processes where local indication is needed. This versatile transmitter features eight field-selectable pressure ranges and comes pre-assembled with a 3-valve manifold for easy installation and maintenance.

Key Features:

• Field-selectable pressure ranges: 10, 20, 50, 100 PSID (unidirectional) and ±10, ±20, ±50, ±100 PSID (bidirectional)
• Integrated LCD display with 4-digit readout and switchable units (WC/kPa)
• Pre-assembled with 3-valve manifold for simplified installation and zero calibration
• Accuracy: ±1.0% for ranges A-C, ±2.0% for range D
• Dual output options: 4-20 mA or (0,1)-5V DC, field-selectable
• Piezoresistive sensor technology with 17-4 stainless steel wetted parts
• Operating temperature range: -4°F to 185°F (-20°C to 85°C)
• Maximum operating pressure (proof): 220 PSID (1,516 kPa)
• Overpressure (burst) protection: 4,000 PSID (27,579 kPa)

The Model 231 series provides field-accessible ranging, choice of output signals, and push-button or remote contact zero adjustment. Compatible with liquids and gases that are compatible with 17-4 stainless steel, this transmitter is ideal for demanding HVAC and industrial applications requiring reliable differential pressure monitoring.
