Electronic Differential Pressure Transmitter 823DP

These 2-wire transmitters provide precision measurement of differential pressure and transmist proportional 4 to 20 or 10 to 50mA dc signals. An intelligent version with remote digital communication capability is also available. 

Standard Features

The 823DP Transmitter includes the following standard features which are normally extra cost options, or not available, with most other brands of transmitters:

• Side Vents and Drains
• RFI Protection
• Voltage Surge Protection
• High-strength B7 Alloy Steel Bolting
• Epoxy Finish
• 20 MPa (3000 psi, 200 kg/cm²) Static Pressure Rating
• Corrosion-resistant Cobalt-Nickel-Chrome Alloy Diaphragms
• NEMA 4X Rating

Performance Specifications

(Transmitter, with cobalt-nickel-chrome alloy sensor diaphragms; at Reference Operating Conditions unless otherwise specified)

Accuracy (Includes linearity, hysteresis, and repeatability): ± 0.2% of calibrated span

Repeatability: 0.05% of calibrated span

Hysteresis: 0.05% of calibrated span

Reproducibility (Includes effects of hysteresis, repeatability, and drift over a 1-hour period): 0/1% of calibrated span

Reference Span The reference span (Table 1) is defined as a commonly used span for each sensor. Performance specifications which vary with calibrated span are also given at the reference span. This provides more useful information than if these specifications were given only at the maximum span.
