Configuration

Single narrow bore capillary

Ranges

Minimum: 0-5CP - Maximum: 0-2500CP

Repeatability

+ 0.5% FS

Precision

±1% FS

Response time

30 seconds to 3 minutes, depending on sample temperature

Measurement temp.

Normally 40-150°C (100-300°F) but 170°C is available (see options)

Output signal

Range (depending on transmitter selected - see options): 4-20 mA fully isolated, loop powered or digital output. Out-of-service alarm contact signalling mains failure (or off) or bath temperature fuse blown.

Local display

0 - 100% linear scale on the transmitter

Temperature bath capacity

11 litres of oil

Use Shell Thermia B or equivalent oil. Normal maximum working temperature of bath is 170°C (protected by thermal fuse). Sample temperature at capillary outlet is measured by spirit-in-glass thermometer.

Cooling water

When sample is at high temperature relative to measuring temperature or when measurement temperature is low with respect to ambient temperature, a supply of cool, potable water (9-45 l/h) should be provided to carry away excess heat. The necessary coil is fitted as standard. If potable water is not available, alternative cooling coil materials can be provided.
