With multiple output options, rugged stainless steel construction, and a compact design, the LP1000 provides a reliable and cost-effective solution for applications requiring precise low-pressure measurement.

Designed for Very Low Pressure Measurement

Measuring low pressure accurately presents unique challenges, including signal noise, drift, and hysteresis. The LP1000 is specifically engineered to overcome these challenges, offering:

• Pressure ranges from 0–50 mbar to 0–1000 mbar

• Excellent low-pressure sensitivity

• Stable and repeatable output

As described on the datasheet’s first page, the LP1000 extends pressure sensing technology into very low-pressure applications while maintaining high performance.

This makes it ideal for applications where precision at low pressures is critical.

Advanced Piezoresistive Sensor Technology

At the core of the LP1000 is a silicon-based piezoresistive sensing element. This technology provides:

• High sensitivity to small pressure changes

• Excellent linearity

• Low hysteresis

• Reliable long-term stability

The advanced sensor design ensures performance characteristics that are not typically achievable in low-pressure measurement systems.

High Accuracy and Low Hysteresis

The LP1000 delivers precise and repeatable measurement performance:

• Accuracy: ±0.5% FS (non-linearity, hysteresis, and repeatability combined)

• Low hysteresis for consistent readings

• Stable output over time

These characteristics are especially important in applications such as leak detection and laboratory testing, where small pressure variations must be accurately measured.

Multiple Output Signal Options

To accommodate a wide range of systems and instrumentation, the LP1000 is available with several output configurations:

• 0–100 mV (non-amplified)

• 0–5 VDC

• 0–10 VDC

• 4–20 mA

This flexibility allows the transducer to be easily integrated into:

• Data acquisition systems

• PLCs and control systems

• Laboratory instrumentation

• Industrial monitoring systems

Robust Stainless Steel Construction

The LP1000 is built with durability in mind:

• Housing: Stainless steel

• Seals: Fluorosilicone

• Sensing element: Silicon

This construction ensures:

• Excellent resistance to corrosion

• Compatibility with air, gases, and compatible liquids

• Long-term reliability in industrial environments

Wide Operating Temperature Range

The LP1000 is designed to perform reliably across a broad temperature range:

• Operating temperature: –20°C to +85°C (–4°F to +185°F)

This allows the sensor to be used in both controlled laboratory environments and more demanding industrial settings.

Adjustable Zero and Span Calibration

The LP1000 includes accessible zero and span adjustment features:

• Fine-tuning of output signal

• Compensation for installation variables

• Improved measurement accuracy

As shown in the datasheet specifications, these adjustments are available via trimming potentiometers on amplified versions.

Excellent Overpressure Protection

The LP1000 is designed to withstand pressure excursions beyond its rated range without damage:

• 4x overpressure protection for lower ranges (50–250 mbar)

• 3x overpressure protection for higher ranges (500–1000 mbar)

This ensures durability and reliability in applications where pressure spikes may occur.

Flexible Process and Electrical Connections

The LP1000 offers standard industrial connection options for easy installation:

Pressure Connections:

• 1/4” BSP male

• 1/2” BSP male

• 1/4” NPT male

Electrical Connection:

• DIN 43650 connector (IP65 rated)

• Optional cable outlet

These options allow the sensor to be easily integrated into existing systems.

Designed for Air, Gas, and Compatible Liquids

The LP1000 is suitable for use with:

• Air

• Non-corrosive gases

• Liquids compatible with stainless steel and silicon

This versatility makes it a practical solution for a wide range of applications.
