PIE 525B Pressure Calibrator
The PIE 525B is a high-precision pressure calibrator designed for calibrating thermocouple (T/C) and RTD instruments. With resolution to 0.01°F and accuracy to 0.2°C, it ensures reliable calibration in demanding industrial environments. This calibrator meets or exceeds AMS 2750 requirements, making it suitable for heat treating surveys and field testing.
Key Features & Highlights
- Versatile T/C Calibration: Supports types J, K, T, E, R, S, B, N, G, C, D, L (J DIN), U (T DIN), and P (Platinel) with millivolt output from -13.000 to 80.000 mV.
- RTD Calibration: Handles Pt 10, 50, 100, 200, 500, and 1000 Ohm (3850), Pt 100 Ohm (alpha=3902, 3916, 3926), Cu 10 and 50 Ohm, and Ni 120 Ohm.
- High Accuracy: Accurate to 0.2°C with cold junction sensor accurate to 0.05°C.
- AMS 2750 Compliance: Meets or exceeds requirements for secondary standard and field test instruments in heat treating.
- RTD Troubleshooting: Automatic detection of 2, 3, or 4 wire connections and indication of open wires; verify operation by measuring excitation current.
- Faster Calibrations: EZ-CHECK switch for instant selection of three outputs, two-speed EZ-DIAL knob, and automatic stepping for easy trip point finding.
- User-Friendly Design: Double-click to select T/C type and °F/°C; low-profile switches resist accidental damage; brass screws and mini T/C socket for connections.
- Easy-to-Read Display: Backlight for dark areas; secondary display shows resistance, compensated millivolt setting, and cold junction temperature.
- Simple Battery Replacement: Uses four inexpensive AA batteries; no tools required.
Applications
The PIE 525B is ideal for calibration labs, maintenance departments, and field service technicians. It is particularly suited for heat treating facilities requiring AMS 2750 compliance, as well as for troubleshooting RTD sensors and verifying instrument operation in plants and shops.
