Product catalog summary

Overview: The document provides technical specifications for the NAT 8252 industrial pressure transmitter by Trafag, suitable for applications like machine tools, hydraulics, HVAC, refrigeration, process technology, and water treatment.

Key Features:

Compact design with a welded steel sensor system without additional seals.
Excellent long-term stability and optional 5-fold overpressure resistance.
Optional switching output with 1 or 2 PNP transistors.

Technical Specifications:

Measuring principle: Thin-film-on-steel.
Accuracy at 25°C: Typically ±0.5% FS.
Measuring range: 0 to 2.5 up to 700 bar (0 to 30 up to 10000 psi).
Media temperature range: -40°C to +125°C.
Output signals: 4-20 mA, 0-5 VDC, 1-5 VDC, etc.
Ambient temperature range: -40°C to +125°C, varying with cable type.

Ordering Information: Includes a type code for ordering, specifying pressure measurement ranges, overpressure, and burst pressure in bar and psi units, with options for fivefold overpressure resistance.

Electrical and Mechanical Connections:

Pressure connections: G1/4” male, 1/4” NPT male, etc.
Electrical connections: Various male connectors.

Output Signals and Accessories: Lists multiple output signal options and compatible accessories like electrical plugs and pressure peak damping elements.

Standard Products: Provides a list of standard products with short lead times, detailing product numbers, type codes, pressure ranges, overpressure limits, supply voltage, and accuracy.

Parameterization: Switching points, delay times, and output functions can be parameterized via a smartphone app, with the SMI Sensor Master Interface available separately.

Specifications: Details electrical data, including output/supply voltage, rise time, power-on delay time, and protection features. Voltage ranges include 28 VDC and a ratiometric range of 0.5 to 4.5 VDC at 14 VDC. Environmental conditions cover media and ambient temperatures from -40°C to +125°C, with specific cable temperature ranges. Protection levels include IP65, IP67, and IP68, with humidity tolerance up to 95% relative. Vibration and shock resistance are specified according to EN standards.

Mechanical Data: Sensor and pressure connection parts are made from 1.4542 (AISI630) stainless steel, housing from 1.4301 (AISI304). Sealing materials include FPM, EPDM, and NBR. Weight is approximately 50 grams, and mounting torque is 25 Nm.

Analogue Output: Accuracy at -25 to +85°C is ±1.75% FS, and at +25°C is ±0.5% FS. Long-term stability over one year is ±0.1% FS. Rise time is typically 1 ms for 10 to 90% nominal pressure.

Switching Output: Similar accuracy specifications as the analogue output. Adjustment range for switchpoints is 1 to 99% FS, with a minimum distance between switchpoint and reset point of ≥1.0% FS. Switching current varies with temperature, with a maximum of 400 mA at -40°C to +85°C and 200 mA at +85°C to +125°C.

Dimensions: Provides various dimensions and configurations for different models, including detailed measurements for connectors and seals.

Protection and Electrical Connection: Details IP protection levels and electrical connection types, including M12x1 and various cable configurations, specifying conditions for achieving different IP ratings.

Additional Information: Links to further documentation, such as data sheets and instructions, are provided for more detailed information.
