Product Overview

The SICK LFH pressure transmitter is a rugged, stainless steel housing-based device designed for continuous hydrostatic level measurement. It operates by detecting the hydrostatic pressure generated by a liquid column above the sensor, providing an accurate and direct indication of liquid level. The probe's robust construction ensures reliable performance in demanding industrial environments. Ideal for applications requiring precise and consistent level monitoring, the LFH transmitter delivers dependable results without mechanical moving parts. Its design emphasizes durability and long-term stability, making it suitable for continuous use in harsh conditions. With a focus on precision and reliability, the LFH pressure probe is engineered to maintain measurement accuracy over time, even under fluctuating operational demands.

Key Features and Technology

The LFH pressure sensor utilizes hydrostatic pressure principles to directly correlate liquid height with pressure, ensuring accurate level readings. The precise measurement technology is embedded within a rugged stainless steel housing, protecting the internal components from physical damage and environmental exposure. Integrated temperature sensing enables real-time monitoring of ambient conditions that may affect measurement accuracy. Surge protection safeguards against voltage spikes, while the cable features highly resistant FEP sheathing—up to 100 meters in standard design—offering excellent resistance to chemical and mechanical stress. This combination ensures stable performance across a range of operational scenarios.

Technical Characteristics

The LFH pressure transmitter includes an integrated temperature sensor for monitoring ambient conditions. It supports a maximum cable length of 250 meters, with the standard design configured at 100 meters. The connecting cable is equipped with FEP sheathing that provides high resistance to chemicals and abrasion. The device features built-in surge protection to prevent damage from transient voltage events. All components are housed in a stainless steel enclosure, ensuring durability and corrosion resistance. These technical attributes ensure reliable operation under varying environmental conditions while maintaining measurement integrity over time.

Configuration and Integration

The LFH pressure transmitter is designed for straightforward integration into existing systems. It features a standard cable connection with a maximum length of 250 meters (standard: 100 m), allowing flexible installation layouts. The integrated temperature measurement provides additional data points for process monitoring. Surge protection ensures compatibility with industrial power environments. The FEP sheathed cable enhances resistance to environmental degradation during installation and operation, reducing the risk of signal loss or damage. No additional external components are required for basic functionality, enabling quick deployment in level measurement applications.
