Pressure Sensor Output.
An on-board pressure sensor module for Texmate's range of modular meters.
A cost effective solution for pressure applications requiring monitoring and process control of non-corrosive, non-ionic working fluids such as air, dry gases and similar. The pressure sensor is available in absolute and differential models and pressure ranges from 0 to 100 psi. The input module interfaces directly with Lynx, Leopard, and Tiger 320 Series meters.

This module interfaces directly with Texmates Tiger, Leopard, and Lynx range of modular controllers and panel meters. It has a single output that is an amplified and scaled v ersion of the onboard direct pressure sensor.
The sensor can be ordered as either an absolute or diff resistors are factory installed to optimize the full scale output f or each pressure range.

Tiger Controllers and Leopard Meter Relays The Tiger and Leopard range use internal software functions to calibrate the span and zero offset. However, it may be necessary to adjust the span potentiometer to bring the maximum input signal within the full scale r ange of the instr ument. The Lynx has no inter nal software calibration procedure. Calibration is done manually using both the zero and span potentiometers.

Overrange Indications
Lynx
When the input signal is be yond the full scale r ange of a L ynx meter, all the segments of each digit of the displa y flashes.
Leopard
When the input signal is be yond the full scale r ange of a Leopard meter, the top segment of each digit on the displa y flashes. See Figure 3.
Tiger
When the input signal is be yond the full scale r ange of a Tiger controller, the display flashes [OVER]. See Figure 3.
Lynx Indicators
Lynx indicators are supplied to match the displa yed full scale counts to the full scale input pressure.
Lynx indicators can displa y the f ollowing resolution for absolute and differential pressure ranges:
Lynx Calibration Example
See Figure 4. For a certain application, a
15 psi pressure input may be required to read 2.00 counts on the meter displa y.
Apply a zero pressure input or zero pressure diff erential. Using the z ero potentiometer, adjust the zero pot until the display reads 0 counts.
Now apply the full scale pressure signal of 15 psi. Using the span potentiometer, adjust the span pot until the displa y reads 2.00 counts.
This procedure can be used to calibr ate a L ynx o ver an y of the specified input ranges b y adjusting the full scale pressure signal and the full scale displa counts to suit.

Leopard Meter Relay Calibration Example In the following example, compressed air is supplied at a constant 80 psi to the pneumatics of an assembly line. If the air pressure becomes greater than 90 psi for an extended period damage can occur to the pneumatic seals.
A Leopard DL-40 meter relay has been installed to monitor the air with an IGYZ universal direct pressure input module set to 100 psi absolute pressure. A setpoint activ ates if the pressure exceeds 90 psi for more than 10 seconds, opens a relief valve, and sounds an alar m.
Figure 6 IGYZ Universal Direct Pressure Sensor Leopard Calibration Example
Procedure
With the compressor off and the air lines open, set the meter s zero calibration setting.
With the isolation v alve closed and only the sample pressure line open, star and take it to 100 psi. With 100 psi at the meter, set the meters span (full scale) setting.
t the compressor
The following example calibration procedure demonstrates calibrating the Leopard DL-40 meter with a zero setting of 0 counts, and a span (full scale) setting of 100 psi. See Figure 7 and the calibration procedure diagram opposite.
The low input source is applied to the meter when setting the zero value.
The high input source is applied to the meter when setting the span value.

Tiger Controller Calibration Example In the following example, a Tiger 320 Series controller has been installed with an IGYZ univ ersal direct pressure input module set to 15 psi differential pressure to monitor the efficiency of a filter mounted in an air duct.If the differential pressure becomes too great, the controller sounds an alarm. See Figure 8.

Procedure
Without the filter in place, zero channel 1.
Now apply 15 psi into the positive (+) differential input tube, while leaving the negative () input tube open to atmosphere.
The f ollowing e xample calibr ation procedure demonstr ates calibr ating the Tiger DI-50 meter with a zero setting of 0 counts, and a span (full scale) setting of 1500 counts for 15 psi on channel 1 (CH1). See Figure 9 and the calibr ation procedure diagram opposite.
