Industrial Pressure Transmitters

We are manufacturing Pressure Transmitters. For high & low pressure measurement (gage and absolute), Instruments & Systems ISP 100 series offers combined linearly repeatability and hysteresis errors that are typically below 0.2 to 1.5% FS of full scale. Instruments & Systems’ ceramic sensing element contains an integral, reliable, solid state, custom hybrid circuit signal conditioner. This circuit provides temperature compensation for a stable output through us of computer-controlled laser trimming of hybrid circuit component. Unit-to-unit uniformity is assured with no calibration required by the user.

Specification:

• Pressure Range: 0-1Bar to 0-400Bar(Gauge and absolute)
• Accuracy: ­ /- 0.25% [non-lineraity repeatability, hysteresis]
• Temperature coefficient [0.1% per 10 deg.C] may be optimized for a specific operating temperature.
• Zero and span adjusted
• Long term stability
• Operating temperature range 40deg. To 125 deg.C /- 0.25%
• Electromagnetic interference [EMI] Protection.

The Smart Series Pressure Transmitters ISP-SMART are piezoresistive pressure sensors. These pressure sensors posses a flush diaphragm facing the pressure media, able to measure the pressures of viscous liquids. The diaphragm forms a chamber in which oil is filled to isolate sensing element from transfer pressure. The isolation helps measure the pressures of corrosive fluids
and electro-conductive fluids.

The HART module can be adjusted via three pushbuttons on display module, PC with HARTTran software
or PDA, Display and push buttons. The indication of the measured value as well as the configuration of
the individual parameters occurs through a menu via the LCD. The individual functionscan be set with
the help of three push buttons. Besides in the display a bar graph is shown, which indicates the current
pressure input in per cent to the specified pressure range.

Following parameters can be adjusted:

• Unlock PV=0
• 4 mA rerange
• 20 mA rerange
• Configuration scaling 
• Damping 
• Display mode
• Fixed output

The Industrial Series Pressure Transmitters  ISP-200 are piezo-resistive pressure sensors based on ceramic. The measuring bridge is printed directly on one side of the ceramic diaphragm by means of thick film technology. Because of the excellent chemical resistance no additional protection is normally required. The sensors are designed in such a way so that temperature changes and overloading do not cause any loss in reliability. The use of ceramic ensures high linearity across the entire range of measurement and reduces effects of hysteresis to a minimum. The sensors are thermal compensated by laser adjustable PTC resistors.
