Level Data Logger PD-3/4/5

Product catalog summary

Overview: The Sommer Level Data Logger series (PD-3, PD-4, PD-5) are advanced instruments designed for measuring water level, temperature, conductivity, and pH-value. These devices are suitable for long-term field use, offering features like data transmission and robust construction.

Specifications:

PD-3: Measures up to two parameters (water level and temperature). It features a memory capacity of over 338,500 records and operates with an integrated lithium battery for up to 10 years or 2,000,000 measurements. The device is compact, with dimensions of Ø 22 mm x 156 mm, and is flood-proof up to 3 m hydrostatic head.
PD-4: Capable of measuring up to four parameters simultaneously. It has a 4 MB memory for up to 520,000 values and uses RS 485 Modbus-connections for input. The device is housed in high-grade stainless steel and is flood-proof up to 3 m hydrostatic head.
PD-5: Similar to PD-4 but includes data transmission capabilities via GSM/GPRS. It supports alarm management and can send alerts via SMS or email. The device has a memory for up to 190,000 values and is flood-proof up to 1.5 m hydrostatic head.

Features and Advantages:

Compact and watertight design suitable for harsh environments.
Long battery life and large data storage capacity.
Data retrieval locally or via transmission (PD-5).
Flexible application in various water management scenarios.

Probes and Accessories:

Water Pressure Probe: Measures water level up to 300 m hydrostatic head and temperature up to +70 °C.
Multiparameter Probe: Measures water level, temperature, and conductivity.
pH-Value Probe: Measures pH-value from 2 to 14 and temperature up to +50 °C.
Accessories include USB transmission cables, user software, and protective caps for level pipes.

Applications: These data loggers are ideal for groundwater management, open water measurements, and use in water reservoirs or tanks. They provide reliable data for efficient water management and monitoring.

Efficient Groundwater Management Sommer level data loggers are considered to be the ideal measuring instruments in oder to record reliably water level and temperature (PD-3) in level pipes and wells. Furthermore, it is possible to collect data of conductivity, pH-value or additional other parameters (PD-4 and PD-5). Moreover, the PD-product family is applicable for measurements in open water, water reservoirs or tanks where it builds a dependable tool for the water management. PD-5 with integrated data transmission In addition to storing the data, the PD-5 is designed to transmit the measurements...
