Product Highlights

The Differential Pressure Transmitter 985 is a versatile instrument designed for accurate pressure measurements. It comes in 2-wire and 3-wire models, with manual or automatic offset calibration, respectively. The setting ranges vary depending on the type, from -100 Pa to 1 bar. The temperature range for the 2-wire model is -20°C to +70°C, while the 3-wire models operate from -10°C to +50°C. The process connection utilises a hose connection with 4/6 mm outer diameter for easy installation. The transmitter requires a supply voltage of 18 to 30 VDC and offers an output signal of either 4-20 mA or 0-10 V, making it compatible with different systems. The electrical connection options include plug-in terminals for wires and strands up to 1.5 mm2 or circular connectors M12/4-pole. Additionally, with a protection class of IP65 according to EN 60529, the Differential Pressure Transmitter 985 ensures durability and resilience in challenging conditions.
