The new Yokogawa CA150 is a multi-function high-precision calibrator designed to calibrate and test industrial process devices and electronics equipment
The Yokogawa CA150 acts as both a source and a measurement unit, with an accuracy within 0.02% of the DC voltage range for both functions.
Source and measurement functions can be carried out simultaneously, so that it is possible to measure current in the milliampere range while providing a loop power supply of up to 24VDC at up to 22mA load.
The CA150 features a vertically oriented body measuring 251x124x70mm, making is easy to use with one hand.
Operation is intuitive, with individual functions being accessed directly by pressing assigned keys.
A large-screen display simultaneous shows source and measurement parameters and units.
Source and measurement functions include DC voltage, DC current, resistance, frequency, temperature (from thermocouple or RTD sensors) and a 24VDC power supply function for powering transmitters.
The CA150 will replace multiple devices such as standard signal generators, variable resistance units and multimeters, which have traditionally been required for applications.
A single CA150 unit makes it possible to perform operational checks, regular inspections, maintenance and diagnostics on equipment such as thermocouples, RTDs, process instruments, transmitters, thermostats and signal converters.
A sink function allows the CA150 to receive current from the power supply at voltages of up to 28VDC while transmitting milliampere DC signals to the loop, while automatic sweep functions include step, linear and programmable sweep.
Both setting and data memory functions are included.
The setting memory is used to save and/or load setting conditions.
Up to 20 [d1] data items can be stored, including settings for source and measurement functions, ranges, generated and measured values and setting-mode conditions.
The data memory saves source and measured values.
Up to 100 data items can be stored, including storage date and time, source and measurement functions, ranges and generated and measured values.
Stored data can be checked on the display of the main unit as well as via the RS232 serial interface.
Power supply is from six AA alkaline batteries giving approximately eight hours operation, a dedicated NiMH battery (sold separately) giving approximately ten hours operation, or an AC adaptor (sold separately).
The unit meets all relevant international safety and EMC standards.
Accessories include a main body case with a strap that allows the CA150 to be hung from the operator's body or attached to a handrail for convenience of use.
