Low Input Bias Current Op Amps (≤100 pA)
-
Low input bias current op amps are required whenever the difference of currents or voltage is small and needs to be measured accurately. These op amps are used so that the signal is not loaded down by the input of the op amps. Low input bias current op amps are critical for interfacing sensors in applications from photodiodes, pH meters, or other electrometer related functions to downstream electronics. Analog Devices has many precision op amps that fit the definition and range of these applications.

Laboratory EM current meter / water level and wave height meter
-
ACM2-RS and ACM3-RS are 2-D and 3-D electro-magnetic current meters for laboratory experiments. The models provide digital output, a high-speed sampling rate and insusceptibility to electro-magnetic noise. ACH-600RS is a highly sensitive capacitance water level meters. With the new system, a maximum of four different sensors can be connected to the compact interface unit, enabling simultaneous recording on a personal computer. Additionally, the system can provide analog output as well as necessary. While conventional water level and wave height meters cannot be used near velocity sensors, our instrument can be as near as 5 cm without increasing noise, due to its special isolated circuit. The result is an innovative system that is capable of achieving highly accurate data.

Flexible Current Sensor Probe
CTA
-
The CTA current sensors convert ac current to an isolated 0-5A current with available ranges from 100A to 10,000A. Because the current sensors are flexible split core, installation is possible without shutting down the LV electrical supply, avoiding expensive down-time costs. Typical applications are retrospective energy monitoring in factories, offices buildings, process control data logging systems, where power, energy and current monitoring is important. Typical applications are factories, offices buildings, ac/dc VFD drives, welding, power conversion and power distribution. For all CTA current sensor models, a NIST/NPL (UKAS) traceable calibration certificate and certificate of conformance is supplied. All CTA sensors use UL94V0 or CSA approved materials. The CTA flexible current sensors are suited to permanent or semi permanent installation. The coil sensor is durable, lightweight, flexible and will easily clip-around a power cable. The 5A output from the CTA current sensor connects direct to installed metering, rotary metering or current transducers.
