Model 276

etra Systems has been a technology

The Model 276 is an extremely accurate

and stable transducer based on the proven

Setraceram

sensing element. The glass

fused ceramic capacitive sensing capsule is

the heart of Setra's environmental pressure

transducers because of its inherent thermal

stability, low hysteresis and fundamentally

simple

design.

Another major feature of the 276 is Setra's

custom Application Speciﬁ c Integrated Circuit

Setraceram

sensor to achieve long-term

stability and high accuracy, unmatched by

other manufacturers - even at a much higher

cost. The ASIC circuit allows the 276 to

operate with an excitation as low as 5 VDC

for rem ote

applications.

(Exc, Out, Com)

Specify One:

Output

12 VDC (9.0 to 14.5) 0.1 to 5.1 VDC**

24 VDC (21.6 to 26.0) 0.1 to 5.1 VDC**

5 VDC (4.9 to 7.1) 0.5 to 4.5 VDC**

Output Impedance 5 ohms

Output Noise <200 microvolts RMS

(0 to 100 Hz)

*There are separate leads for +Exc, -Exc, +Out, -Out. The -Exc and -Out are

commoned internally. The shield is connected to the case. For best perfor-

mance, either the -Exc or -Out should be connected to the case. Unit is

calibrated at the factory with the -Exc connected to the case. The insulation

resistance between all signal leads tied together and case ground is 100

megohms minimum at 25 VDC.

**Zero and Full Scale Outputs are factory set to within ±0.25% Full Scale.
