Thermo Scientific™ HME900:
The durable HME900 head-mounted density converter may be included with any Thermo Scientific liquid or gas density meter or specific gravity analyzer. This unit conditions the output signal to provide a HART compatible 4-20mA signal that can be connected directly to the user's DCS or it can be read digitally. An optional local display enables viewing of the prime variable value either in engineering units alone or with an alternating display of percent of chosen span. The HME900 is ideal for most general density measurement applications and where HART communications are required.
Thermo Scientific CM515 (formerly CM200):
The versatile CM515 density converter accepts inputs from Thermo Scientific density meters. This easy-to-use device derives density at reference conditions, calculates density derived parameters and is compatible with a wide range of density meter pulse outputs. Parameters and calibration data can be monitored using either the RS-232 or RS-485 interface option. The CM515 is best suited to applications that require a greater degree of input/output flexibility than offered by the HME900 or when HART compatibility is not required.
