Sarasota Density Electronics |
| |
 |
|
The Sarasota HME900 headmounted electronics option can be fitted to all density meters in the range and gives the user the power of control room electronics in the field with full HART compatibility. For applications requiring greater input/output flexibility or where the electronics are control room based, users may prefer the Sarasota CM200 panel mounted density converter.
The HME900 accepts period and thermometry signals from the density transducer plus, when required, a pressure signal from a pressure transducer enabling the full range of density calculations. The HME900 electronics will provide a loop powered 4-20mA output relative to density or a derived parameter with full HART compatibility.
The CM200 interfaces with all common field transmitters and offers both a printer and communications interface (RS232/RS485). It performs a number of density converter and flow computing calculations and is user configurable.
