Precision Pressure Transducer –
Explosion Proof
PPTE
Honeywell’s PPTE offers an explosion-proof pressure transducer where protection in hazardous locations is critical.
It combines proven silicon sensor technology with microprocessor-based signal conditioning to provide an extremely
smart pressure transducer. Designed with a hermetically sealed, stainless steel construction, the PPTE operates in
severe vibration, thermal and mechanical shock environments. The PPTE has many software features that support a
wide range of applications.

(1) Accuracy is the sum of worst case linearity, repeatability,
hysteresis, thermal effects and calibration errors from -40 to
85ºC. Typical is the average of absolute value of errors at
all pressures and temperatures. Calibration is traceable to
NIST. (2) Tighter accuracy available on some models.
Consult factory. (3) Exposure to overpressure will not
permanently affect calibration or accuracy of unit.
Exceeding burst pressure may result in media escape.
Mechanical Shock tested per MIL-STD-883D, M2002.3,
Cond. B. Vibration tested per MIL-STD-883D, M2007.2,
Cond. A. (4) User configurable.
