High Temperature Pressure Transmitter

for Biotechnology / Food-Industries

This piezoresistive high temperature transmitter is suited for media temperatures up to 300 °C.

The pressure, acting onto the flush diaphragm, is transferred over an oil-filled capillary onto

the silicon measuring cell. The capillary has the function of a cooling spiral, allowing media

temperatures of up to 300 °C. The temperature of the electronics, which can be read out with

the PROG30 software, may not exceed 120 °C. For highly aggressive media, KELLER offers

pressure ports in different materials.

Digital Output of Transmitter

These Series are based on the stable, piezoresisitive transducer and a micro-processor electro-

nics with integrated 16 bit A/D converter. Temperature dependencies and non-linearities of the

sensor are mathematically compensated. With the READ30 software and the KELLER cable

K-107, the calculated pressure can be displayed on a Palmtop, Laptop or PC. The READ30

software also allows the recording of pressure signals and the graphic display on the PC. Up to

128 transmitters can be hooked together to a Bus-system.

Transmitter with Analog Output

The micro-processor integrates a D/A converter of 16 bit for analog signal outputs of 4…20 mA

or 0…10 V. The output rate is 100 Hz (adjustable). The digital output is available on all transmit-

ters with analog output.

Programming

With the KELLER software READ30 and PROG30, a RS485 converter (i.e. K-102, K-104 or

K-107 from KELLER) and a PC, the pressure can be displayed, the units changed, a new gain or

zero set. The analog output can be set to any range within the compensated range.

written into the EEPROM of the microprocessor.

When the pressure transmitter is in service, the

microprocessor measures the signals (S) and

(T), calculates the coefficients according to the

temperature and produces the exact pressure

value by solving the P(S,T) equation.

Calculations and conversions are performed at

least 400 times per second.

Accessories Series 30

Each Series 30 transmitter also integrates a digital interface (RS485 halfduplex) which you can make use of: Connect the transmitter to a PC or

Laptop via a converter RS232-RS485 (i.e. K-102, K-104 or K-107). Two programs are offered:

READ30: Data collection with graphs

• Fast read-out and viewing of the pressure

•

Call up of information (pressure- and tempe-

signals in a graph

rature range, version of software etc.)

• Documentation of dynamic measurements

• Indication of actual pressure value

• Up to 16 transmitters on one serial connec-

• Selection of the units

tion (Bus-operation)

•

Setting of a new zero and gain for the

transmitter

• Reprogramming of the analog output

(i.e. different unit, other pressure range)

• Programming of the switch output

• Changing the output rate

You can also tie up the transmitters into your own software. You have then a documentation,

a DLL and numerous examples at your disposal.

Changing the plug connector (optional)

Laboratory applications require the same transmitter to be used at different measurement points with different electrical connection arrange-

ments. To accommodate such applications, KELLER can supply different connectors matching with the internal standard plug. This makes it

easy to exchange the electrical connector of the transmitter.
