ORDERING INFORMATION
To place an order, please use the ordering code format
as shown on the left. Also specify a measuring
temperature range*.
(e.g.) MS5501-A-KA (0 to 500°C)* Note that the temperature range should be specified insteps of at least 10 degrees Celsius.
Other Ordering Examples:
For an input code of “0”: MS5501-A-0A (WRe5-26, 0 to2000°C)
For an output code of “0”: MS5501-A-K0 (0 to 500°C /Output: 2 to 5V)
For an option code of “X”: MS5501-A-K6/X (0 to 500°C /Burnout drive time: 500ms max.)Note: If you wish to include multiple options in your order,
specify the option codes in series (e.g. /KX).
