DESCRIPTION

The Model 88F is a durable, full featured, flush diaphragm pressure transmitter. It is designed to mount flush against process media and to prevent any media particles, such as from paper slurry, from collecting at the diaphragm. Its rugged 316 stainless steel and Hastelloy C construction make it perfect for tough environments and corrosive media conditions.

The compact size and weight of the Model 88F transmitter eliminate any complicated mounting hardware and mechanical supports.

The integral junction box permits simple field wiring, too. All of this reduces your installation time substantially. And with the cover retained by a stainless steel chain and no internal jumpers for span turndown, losses due to misplaced or dropped parts are eliminated.

A 4-20 mA output is standard with a 12-40 VDC power supply.  Approvals include FM and CSA for both intrinsic safety and explosion proof ratings: CENELEC approval for intrinsic safety is also available.  The Model 88F also meets NACE standards.

Pressure Range 002 = 0/3 to 0/15 psi (0/.2) to 0/1 bar)
003 = 0/6 to 0/30 psi (0./4 to 0/2 bar)
004 = 0/20 to 0/100 psi (0/1.4 to 0/7 bar)
005 = 0/60 to 0/300 psi (0/4 to 0/20 bar)
Material        Base      Diaphragm      Fill
A =    316SS     Hastelloy C    Silicone Oil
Output 2 = 4 - 20 mADC
Approval FM & CS = Either code acceptable. Approved by Factory Mutual & Canadian Standard Assoc. for I.S. and Exp. Proof
CL = Approved by CENELEC to I.S. only
Coupling SC = 316 SS Coupling; Teflon Gasket
PC = 316 SS Plug and Coupling; Teflon Gasket
NC = No Coupling; Teflon Gasket
Calibration Range (specify)
Will be calibrated at maximum range in psi if not specified.

Example:

88F-004-A-2-CS-(0 to 75 psi)
Model 88F Pressure Transmitter, 100 psi max. range, 316 SS base, Hastelloy C diaphragm, silicone oil fill, output at 4-20 mADC, CSA and FM approved, 316 SS plug and coupling and calibrated so 0 to 75 psi pressure gives 4 to 20 mADC output.
