The SPC98 dry and flush mounted ceramic pressure sensor uses an aluminum oxide ceramic sensor as a "dry cell" that is extremely resistant to overload, aggressive mediums, extreme min/max temperature, applications with solid particles and low pressure ranges. These transmitter's are made in either 316 S.S. or Hastelloy C and provide a 4-20mA output signal. The SPC98 is designed to be installed at the bottom of the tank.
FEATURES
*Loop powered, 4-20mA signal output
*Measuring ranges -1 to 580PSI (-1 to 40 bar) gauge /absolute
*Ideal for waste water or other applications with "dirty" medium
*Rugged and compact design- Body entirely 316 S.S. or Hasteloy C
*High accuracy, Excellent repeatability & Temperature compensated
*3A approved
The actual measuring range of the SPC98 sensor is determined by the thickness of the ceramic diaphragm, which if overloaded, stops on the ceramic substrate without sustaining damage. Ceramic cells do not expand and contract nearly as much as metal, ensuring good temperature stability. Common features of the SPC98 are low hysteresis, high repeatability, immunity to the effects of process builds up and outstanding resistance to chemical attack.

Comprehensive isolating diaphragm program
High resistance diaphragm materials
Product temperature up to 400 °C
Function
The separating diaphragms of the sensor are deflected by the existing pressures. The filling oil transmits the pressure to a semiconductor measuring bridge, the differential pressure dependent output signal of which is measured and further processed. The advantages of this sensor are the high system pressure up to 420 bar, the excellent longterm stability and the very high, unilateral overload resistance.

P 26
Intelligent differential pressure transducer
with scalable measurement range.
Sensitive measurement technology in innovative housing
Demands for increased quality in nearly every area of industry have subjected pressure gauges to sophisticated demands as well. These include clean room monitoring and the ability to monitor sterile environments in the packaging machines used in products for such industries as foods and pharmaceuticals. The new P 26 differential pressure transducer from halstrup-walcher has been specially designed to meet these demands.
The P 26 is a differential pressure transducer that meets these particularly sophisticated demands. Measurement ranges between 100 Pa and 100 kPa are freely scalable from 10 to 100%, and provide the option of switching to other units of measurement like mmH2O, mmHg, etc. Cyclical self-calibration of the zero point ensures a high level of measurement stability. Two cutoff points are available that can be set freely along the entire measurement range; these allow the user to connect visual or audible alarms that would be triggered any time values fall above or below limits. All measurement values can be clearly read on an optional graphic LCD. The instrument can, if necessary, communicate with a master control unit via an RS 232 interface and can be mounted either on a wall or on top-hat rails.
A hand-held unit can be used as a configurator for the one-time calibration when using more than one of the affordable P 26 pressure transducer without a display.

Differential pressure transmitter type FDA602D
This measures the differential pressure in liquid and gaseous
media indirectly using two absolute pressure sensors.
This makes it less expensive but more robust with respect to
asymmetrical overload.
The differential pressure range should be at least 5% of the
standard pressure range.
Each side of the sensor incorporates two pressure
connections. The transmitters can thus be used easily and
conveniently in pressure pipes.
It incorporates a high-speed, high-precision microprocessor.
All reproducible errors affecting the pressure sensors, i.e.
involving non-linearity and temperature dependency, can be
completely eliminated by means of mathematical error
compensation.
