.jpg) | SR50A The SR50A measures the distance from the sensor to a target. The most common applications are measuring snow depths and water levels. The sensor is based on an electronic transducer that determines the distance to a target by sending out ultrasonic pulses and measuring the time it takes for the echoes to return. | ||
.jpg) | CS408 The CS408 is a submersible pressure transducer manufactured by Pressure Systems to measure surface water, ground water, or hostile fluid levels. Each transducer is individually calibrated, and ships with a calibration sheet. The sheet specifies I/O conditions, as well as actual data reflecting the unit’s static accuracy and thermal characteristics. A vent tube, which runs the entire length of the cable, vents to the atmosphere so the measurements do not have to be corrected for barometric pressure. | ||
.jpg) | CS410 The CS410 is a shaft encoder designed for water level measurements. A pulley attached to a a float and counter-weight rotates as water level rises or falls, and the shaft encoder sends two pulse strings to the datalogger. The datalogger records the pulse strings, and the water level is calculated by adding and subtacting the clockwise or counter clockwise movement to a running total. | ||
.jpg) | CS420 The CS420 submersible pressure transducer is manufactured by Druck for use in surface, ground water, or hostile fluid applications. Changes in water level correspond to pressure changes on a strain gage bonded to a pressure-sensitive diaphragm. When a precision excitation voltage is applied, the electrical resistance varies with changing liquid pressure. Our dataloggers supply the excitation voltage and measure resistance, then convert the measured value to the desired units (i.e., pressure, depth, or level). | ||
| CS425 The CS425 submersible pressure transducer is manufactured by Druck for use in surface, ground water, or hostile fluid applications. Changes in water level correspond to pressure changes on a strain gage bonded to a pressure-sensitive diaphragm. When a precision excitation voltage is applied, the electrical resistance varies with changing liquid pressure. Our dataloggers supply the excitation voltage and measure resistance, then convert the measured value to the desired units (i.e., pressure, depth, or level). | ||
.jpg) | CS431 The CS431, manufactured by Instrumentation Northwest for use with Campbell Scientific dataloggers, measures both water level and water temperature. It uses piezoresistive strain gage technology to measure water level and an on-board thermistor to measure water temperature. The CS431 has a 316 stainless steel body and Viton® and Teflon® wire seals that resist corrosion. Its double-sealed, cable harness protects the cable jacket and reduces the possibility of leakage. The end cone is interchangeable with an NPT inlet. | ||
.jpg) | CS440 The CS440 submersible pressure transducer is manufactured by ACData Solutions, Inc., to provide liquid level measurements in wells, lakes, streams, and tanks. The pressure transducer uses an isolated silicon strain gauge sensor housed in a 316 Stainless Steel package. The rugged, polyurethane cable jacket remains flexible under harsh conditions. The cable incorporates a vent tube to compensate for atmospheric pressure fluctuations. The vent tube terminates inside a desiccated chamber to prevent moisture from entering the system. | ||

The transducer uses an isolated silicon strain gauge sensor housed in a 316 Stainless Steel package. The rugged, polyurethane cable jacket remains flexible under harsh conditions. The cable incorporates a vent tube to compensate for atmospheric pressure fluctuations. The vent tube terminates inside a desiccated chamber to prevent moisture from entering the system. | ||
.jpg) | DB1 The DB1 is a self-calibrating system that measures water level (or other liquids), such as measurement in channels and stilling wells. It detects level by measuring the pressure required to force nitrogen bubbles from a pair of submerged tubes. The orifices of the tubes are separated by a fixed vertical distance. The pressure line that is measured is determined by the datalogger, which opens and closes valves on the manifold assembly. A single pressure transducer measures each of the tubes, as well as the atmospheric pressure. | ||
.jpg) | 107 The 107 is a general purpose sensor that can be used to accurately measure the temperature of a variety of media, most commonly air, water, and soil. The 107 temperature sensor consists of a thermistor encapsulated in a cylindrical aluminum housing. The probe measures temperature from -35° to +50°C and is designed for durability and ease of installation/removal. | ||
.jpg) | 108 The 108 is a general purpose temperature sensor that can be used to accurately measure the temperature of a variety of media, most commonly air, water, and soil. The 108 consists of a thermistor encapsulated in a cylindrical aluminum housing. The probe measures temperature from -5° to +95°C and is designed for durability and ease of installation/removal. | ||
| 109 The 109-L Temperature Probe is a thermistor used with our CR200-series dataloggers. The CR200-series dataloggers have a special instruction for measuring the 109 probe. The 109 is designed to measure the temperature of air, water, or soil. For air temperature measurements, the 41303-5A solar radiation shield is typically used to house the probe, while limiting solar loading on the sensor. | ||
