Model 370

Product catalog summary

Overview: The Setra Models 370 and 470 are high-accuracy digital pressure measurement instruments, utilizing the SETRACERAM™ sensor and advanced microprocessor technology to achieve system accuracy better than ±0.02% full scale. These models are widely used in environmental monitoring and test & measurement systems globally.

Model 370 Features: This model includes a 6-digit LCD for displaying pressure and altitude data, accessible via a bidirectional RS-232 port. It features a numeric keypad for engineering unit conversions, min/max tracking, alarm setpoints, nonlinear functions, and calibration procedures. An optional rechargeable battery pack is available for field use.

Model 470 Features: Functionally similar to the 370, the 470 is designed for applications not requiring a local display or keypad access. It is favored for weather observation systems due to its stability and reliability. Both models support programmable data output via RS-232 at adjustable baud rates.

Applications: These models are suitable for automatic weather reporting systems, pressure transfer standards, altimeter calibration recertification, lab or production process monitoring, and altitude chambers.

Specifications:

Pressure Ranges: Barometric (600 to 1100 hPa/mb), Absolute (0 to 100 psia)
Accuracy: ±0.02% FS at 70°F
Non-Linearity: ±0.012% FS
Hysteresis: 0.010% FS
Thermal Effects: Compensated range from +32 to +110°F
Stability: 0.005% FS over 24 hours, 0.05% FS over 1 year

Performance Data: The models offer high resolution and stability, with features like digital altimeter setting indicators and corrected altimeter modes. They are calibrated at 70°F with traceability to NIST standards.

Physical Description:

Model 370: Includes a 1/8" - 27 NPT internal pressure fitting, weighs 12 lbs with battery pack.
Model 470: Features a barbed fitting for 1/8" I.D. tubing, weighs approximately 2.4 lbs.

Ordering Information: Specify pressure range and options when ordering. Setra's quality standards are based on ANSI-Z540-1, ensuring NIST traceable calibration.
